+---
+
+## Before you begin
+
+This guide assumes you have already done the following:
+
+1. Installed [Go (v1.24.2 or higher)].
+1. Installed [PostgreSQL 16+ and the `psql` client][install-postgres].
+
+### Cloud Setup (Optional)
+
+If you plan to use **Google Cloud’s Vertex AI** with your agent (e.g., using Gemini or PaLM models), follow these one-time setup steps:
+
+1. [Install the Google Cloud CLI]
+1. [Set up Application Default Credentials (ADC)]
+1. Set your project and enable Vertex AI
+
+    ```bash
+    gcloud config set project YOUR_PROJECT_ID
+    gcloud services enable aiplatform.googleapis.com
+    ```
+
+[Go (v1.24.2 or higher)]: https://go.dev/doc/install
+[install-postgres]: https://www.postgresql.org/download/
+[Install the Google Cloud CLI]: https://cloud.google.com/sdk/docs/install
+[Set up Application Default Credentials (ADC)]: https://cloud.google.com/docs/authentication/set-up-adc-local-dev-environment
+
+
+## Step 1: Set up your database
+
+In this section, we will create a database, insert some data that needs to be
+accessed by our agent, and create a database user for Toolbox to connect with.
+
+1. Connect to postgres using the `psql` command:
+
+    ```bash
+    psql -h 127.0.0.1 -U postgres
+    ```
+
+    Here, `postgres` denotes the default postgres superuser.
+
+    {{< notice info >}}
+
+#### **Having trouble connecting?**
+
+* **Password Prompt:** If you are prompted for a password for the `postgres`
+  user and do not know it (or a blank password doesn't work), your PostgreSQL
+  installation might require a password or a different authentication method.
+* **`FATAL: role "postgres" does not exist`:** This error means the default
+  `postgres` superuser role isn't available under that name on your system.
+* **`Connection refused`:** Ensure your PostgreSQL server is actually running.
+  You can typically check with `sudo systemctl status postgresql` and start it
+  with `sudo systemctl start postgresql` on Linux systems.
+
+<br/>
+
+#### **Common Solution**
+
+For password issues or if the `postgres` role seems inaccessible directly, try
+switching to the `postgres` operating system user first. This user often has
+permission to connect without a password for local connections (this is called
+peer authentication).
+
+```bash
+sudo -i -u postgres
+psql -h 127.0.0.1
+```
+
+Once you are in the `psql` shell using this method, you can proceed with the
+database creation steps below. Afterwards, type `\q` to exit `psql`, and then
+`exit` to return to your normal user shell.
+
+If desired, once connected to `psql` as the `postgres` OS user, you can set a
+password for the `postgres` *database* user using: `ALTER USER postgres WITH
+PASSWORD 'your_chosen_password';`. This would allow direct connection with `-U
+postgres` and a password next time.
+    {{< /notice >}}
+
+1. Create a new database and a new user:

+  For a real application, it's best to follow the principle of least permission
+  and only grant the privileges your application needs.

+
+    ```sql
+      CREATE USER toolbox_user WITH PASSWORD 'my-password';
+
+      CREATE DATABASE toolbox_db;
+      GRANT ALL PRIVILEGES ON DATABASE toolbox_db TO toolbox_user;
+
+      ALTER DATABASE toolbox_db OWNER TO toolbox_user;
+    ```
+
+1. End the database session:
+
+    ```bash
+    \q
+    ```
+
+    (If you used `sudo -i -u postgres` and then `psql`, remember you might also
+    need to type `exit` after `\q` to leave the `postgres` user's shell
+    session.)
+
+1. Connect to your database with your new user:
+
+    ```bash
+    psql -h 127.0.0.1 -U toolbox_user -d toolbox_db
+    ```
+
+1. Create a table using the following command:
+
+    ```sql
+    CREATE TABLE hotels(
+      id            INTEGER NOT NULL PRIMARY KEY,

+      checkout_date DATE    NOT NULL,
+      booked        BIT     NOT NULL
+    );
+    ```
+
+1. Insert data into the table.
+
+    ```sql
+    INSERT INTO hotels(id, name, location, price_tier, checkin_date, checkout_date, booked)
+    VALUES
+      (1, 'Hilton Basel', 'Basel', 'Luxury', '2024-04-22', '2024-04-20', B'0'),

+    ```
+
+1. End the database session:
+
+    ```bash
+    \q
+    ```
+
+## Step 2: Install and configure Toolbox
+
+In this section, we will download Toolbox, configure our tools in a
+`tools.yaml`, and then run the Toolbox server.
+
+1. Download the latest version of Toolbox as a binary:
+
+    {{< notice tip >}}
+  Select the
+  [correct binary](https://github.com/googleapis/genai-toolbox/releases)
+  corresponding to your OS and CPU architecture.
+    {{< /notice >}}
+    <!-- {x-release-please-start-version} -->
+    ```bash
+    export OS="linux/amd64" # one of linux/amd64, darwin/arm64, darwin/amd64, or windows/amd64
+    curl -O https://storage.googleapis.com/genai-toolbox/v0.9.0/$OS/toolbox
+    ```
+    <!-- {x-release-please-end} -->
+
+1. Make the binary executable:
+
+    ```bash
+    chmod +x toolbox
+    ```
+
+1. Write the following into a `tools.yaml` file. Be sure to update any fields
+   such as `user`, `password`, or `database` that you may have customized in the
+   previous step.
+
+    {{< notice tip >}}
+  In practice, use environment variable replacement with the format ${ENV_NAME}
+  instead of hardcoding your secrets into the configuration file.

+
+    For more info on tools, check out the `Resources` section of the docs.
+
+1. Run the Toolbox server, pointing to the `tools.yaml` file created earlier:
+
+    ```bash
+    ./toolbox --tools-file "tools.yaml"
+    ```
+  {{< notice note >}}
+    Toolbox enables dynamic reloading by default. To disable, use the `--disable-reload` flag.
+  {{< /notice >}}
+
+## Step 3: Connect your agent to Toolbox
+
+In this section, we will write and run an agent that will load the Tools
+from Toolbox.
+
+1. Initialize a go module:
+
+    ```bash
+    go mod init main
+    ```
+
+1. In a new terminal, install the [SDK](https://pkg.go.dev/github.com/googleapis/mcp-toolbox-sdk-go).
+
+    ```bash
+    go get github.com/googleapis/mcp-toolbox-sdk-go
+    ```
+
+1. Create a new file named `hotelagent.go` and copy the following code to create an agent:
+
+    {{< tabpane persist=header >}}
+{{< tab header="LangChain Go" lang="go" >}}

+## Use Tools
+
+Your AI tool is now connected to AlloyDB using MCP. Try asking your AI assistant to create a database, cluster or instance.
+
+The following tools are available to the LLM:
+
+1. **alloydb-create-cluster**: creates alloydb cluster
+1. **alloydb-create-instance**: creates alloydb instance (PRIMARY, READ_POOL or SECONDARY)
+1. **alloydb-get-operation**: polls on operations API until the operation is done.
+
+{{< notice note >}}
+Prebuilt tools are pre-1.0, so expect some tool changes between versions. LLMs will adapt to the tools available, so this shouldn't affect most users.
+{{< /notice >}}
+
+## Connect to your Data
+
+After setting up an AlloyDB cluster and instance, you can [connect your IDE to the database](https://cloud.google.com/alloydb/docs/pre-built-tools-with-mcp-toolbox).

+security rules.
+
+The following tools are available to the LLM:
+
+1. **firestore-get-documents**: Gets multiple documents from Firestore by their paths
+1. **firestore-list-collections**: List Firestore collections for a given parent path
+1. **firestore-delete-documents**: Delete multiple documents from Firestore
+1. **firestore-query-collection**: Query documents from a collection with filtering, ordering, and limit options
+1. **firestore-get-rules**: Retrieves the active Firestore security rules for the current project
+1. **firestore-validate-rules**: Validates Firestore security rules syntax and errors
+

+  Connect your IDE to Looker using Toolbox.

+
+[Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) is
+an open protocol for connecting Large Language Models (LLMs) to data sources
+like Postgres. This guide covers how to use [MCP Toolbox for Databases][toolbox]
+to expose your developer assistant tools to a Looker instance:
+
+* [Cursor][cursor]
+* [Windsurf][windsurf] (Codium)
+* [Visual Studio Code][vscode] (Copilot)
+* [Cline][cline] (VS Code extension)
+* [Claude desktop][claudedesktop]
+* [Claude code][claudecode]

+[cline]: #configure-your-mcp-client
+[claudedesktop]: #configure-your-mcp-client
+[claudecode]: #configure-your-mcp-client
+
+## Set up Looker
+
+1. Get a Looker Client ID and Client Secret. Follow the directions
+   [here](https://cloud.google.com/looker/docs/api-auth#authentication_with_an_sdk).
+
+1. Have the base URL of your Looker instance available. It is likely
+   something like `https://looker.example.com`. In some cases the API is
+   listening at a different port, and you will need to use
+   `https://looker.example.com:19999` instead.
+
+## Install MCP Toolbox
+
+1. Download the latest version of Toolbox as a binary. Select the [correct
+   binary](https://github.com/googleapis/genai-toolbox/releases) corresponding

+# Firestore Source
+
+[Firestore][firestore-docs] is a NoSQL document database built for automatic
+scaling, high performance, and ease of application development. While the
+Firestore interface has many of the same features as traditional databases,
+as a NoSQL database it differs from them in the way it describes relationships
+between data objects.
+
+If you are new to Firestore, you can [create a database and learn the
+basics][firestore-quickstart].
+
+[firestore-docs]: https://cloud.google.com/firestore/docs
+[firestore-quickstart]: https://cloud.google.com/firestore/docs/quickstart-servers
+
+## Requirements
+
+### IAM Permissions
+
+Firestore uses [Identity and Access Management (IAM)][iam-overview] to control
+user and group access to Firestore resources. Toolbox will use your [Application
+Default Credentials (ADC)][adc] to authorize and authenticate when interacting
+with [Firestore][firestore-docs].
+
+In addition to [setting the ADC for your server][set-adc], you need to ensure
+the IAM identity has been given the correct IAM permissions for accessing
+Firestore. Common roles include:
+- `roles/datastore.user` - Read and write access to Firestore
+- `roles/datastore.viewer` - Read-only access to Firestore
+- `roles/firebaserules.admin` - Full management of Firebase Security Rules for Firestore. This role is required for operations that involve creating, updating, or managing Firestore security rules (see [Firebase Security Rules roles][firebaserules-roles])
+
+See [Firestore access control][firestore-iam] for more information on
+applying IAM permissions and roles to an identity.

+
+### Database Selection
+
+Firestore allows you to create multiple databases within a single project. Each
+database is isolated from the others and has its own set of documents and
+collections. If you don't specify a database in your configuration, the default
+database named `(default)` will be used.
+
+## Example
+
+```yaml
+sources:
+  my-firestore-source:
+    kind: "firestore"
+    project: "my-project-id"
+    # database: "my-database"  # Optional, defaults to "(default)"

+### Map Parameters
+
+The map type is a collection of key-value pairs. It can be configured in two ways:
+
+- Generic Map: By default, it accepts values of any primitive type (string, integer, float, boolean), allowing for mixed data.
+- Typed Map: By setting the valueType field, you can enforce that all values
+  within the map must be of the same specified type.
+
+#### Generic Map (Mixed Value Types)
+
+This is the default behavior when valueType is omitted. It's useful for passing a flexible group of settings.
+
+```yaml
+    parameters:
+          - name: execution_context
+            type: map
+            description: A flexible set of key-value pairs for the execution environment.
+```
+
+#### Typed Map
+
+Specify valueType to ensure all values in the map are of the same type. An error
+will be thrown in case of value type mismatch.
+
+```yaml
+ parameters:
+      - name: user_scores
+        type: map
+        description: A map of user IDs to their scores. All scores must be integers.
+        valueType: integer # This enforces the value type for all entries.

+# firestore-query-collection
+
+The `firestore-query-collection` tool allows you to query Firestore collections with filters, ordering, and limit capabilities.
+
+## Configuration
+
+To use this tool, you need to configure it in your YAML configuration file:
+
+```yaml
+sources:
+  my-firestore:
+    kind: firestore
+    config:
+      project: my-gcp-project
+      database: "(default)"
+
+tools:
+  query_collection:
+    kind: firestore-query-collection
+    source: my-firestore
+    description: Query Firestore collections with advanced filtering
+```
+
+## Parameters
+
+| Parameter | Type | Required | Default | Description |
+|-----------|------|----------|---------|-------------|
+| `collectionPath` | string | Yes | - | The path to the Firestore collection to query |
+| `filters` | array | No | - | Array of filter objects (as JSON strings) to apply to the query |
+| `orderBy` | string | No | - | JSON string specifying field and direction to order results |
+| `limit` | integer | No | 100 | Maximum number of documents to return |
+| `analyzeQuery` | boolean | No | false | If true, returns query explain metrics including execution statistics |
+
+### Filter Format
+
+Each filter in the `filters` array should be a JSON string with the following structure:
+
+```json
+{
+  "field": "fieldName",
+  "op": "operator",
+  "value": "compareValue"
+}
+```
+
+Supported operators:
+- `<` - Less than
+- `<=` - Less than or equal to
+- `>` - Greater than
+- `>=` - Greater than or equal to
+- `==` - Equal to
+- `!=` - Not equal to
+- `array-contains` - Array contains a specific value

+
+## Example Usage
+
+### Query with filters
+
+```json
+{
+  "collectionPath": "users",
+  "filters": [
+    "{\"field\": \"age\", \"op\": \">\", \"value\": 18}",
+    "{\"field\": \"status\", \"op\": \"==\", \"value\": \"active\"}"
+  ],
+  "orderBy": "{\"field\": \"createdAt\", \"direction\": \"DESCENDING\"}",
+  "limit": 50
+}
+```
+
+### Query with array contains filter
+
+```json
+{
+  "collectionPath": "products",
+  "filters": [
+    "{\"field\": \"categories\", \"op\": \"array-contains\", \"value\": \"electronics\"}",
+    "{\"field\": \"price\", \"op\": \"<\", \"value\": 1000}"
+  ],
+  "orderBy": "{\"field\": \"price\", \"direction\": \"ASCENDING\"}",
+  "limit": 20
+}
+```
+
+### Query with IN operator
+
+```json
+{
+  "collectionPath": "orders",
+  "filters": [
+    "{\"field\": \"status\", \"op\": \"in\", \"value\": [\"pending\", \"processing\"]}"
+  ],
+  "limit": 100
+}
+```
+
+### Query with explain metrics
+
+```json
+{
+  "collectionPath": "users",
+  "filters": [
+    "{\"field\": \"age\", \"op\": \">=\", \"value\": 21}",
+    "{\"field\": \"active\", \"op\": \"==\", \"value\": true}"
+  ],
+  "orderBy": "{\"field\": \"lastLogin\", \"direction\": \"DESCENDING\"}",
+  "limit": 25,
+  "analyzeQuery": true
+}
+```
+
+## Response Format
+
+### Standard Response (analyzeQuery = false)
+
+The tool returns an array of documents, where each document includes:
+
+```json
+{
+  "id": "documentId",
+  "path": "collection/documentId",
+  "data": {
+    // Document fields
+  },
+  "createTime": "2025-01-07T12:00:00Z",
+  "updateTime": "2025-01-07T12:00:00Z",
+  "readTime": "2025-01-07T12:00:00Z"
+}
+```
+
+### Response with Query Analysis (analyzeQuery = true)
+
+When `analyzeQuery` is set to true, the tool returns a single object containing documents and explain metrics:
+
+```json
+{
+  "documents": [
+    // Array of document objects as shown above
+  ],
+  "explainMetrics": {
+    "planSummary": {
+      "indexesUsed": [
+        {
+          "query_scope": "Collection",
+          "properties": "(field ASC, __name__ ASC)"
+        }
+      ]
+    },
+    "executionStats": {
+      "resultsReturned": 50,
+      "readOperations": 50,
+      "executionDuration": "120ms",
+      "debugStats": {
+        "indexes_entries_scanned": "1000",
+        "documents_scanned": "50",
+        "billing_details": {
+          "documents_billable": "50",
+          "index_entries_billable": "1000",
+          "min_query_cost": "0"
+        }
+      }
+    }
+  }
+}
+```
+
+## Error Handling
+
+The tool will return errors for:
+- Invalid collection path
+- Malformed filter JSON
+- Unsupported operators
+- Query execution failures
+- Invalid orderBy format

+
+```json
+{
+  "valid": "boolean",      
+  "issueCount": "number",
+  "formattedIssues": "string",
+  "rawIssues": [
+    {
+      "sourcePosition": {
+        "fileName": "string",
+        "line": "number",
+        "column": "number",
+        "currentOffset": "number",
+        "endOffset": "number"
+      },

+### Example response with errors
+
+```json
+{
+  "valid": false,
+  "issueCount": 1,
+  "formattedIssues": "Found 1 issue(s) in rules source:\n\nERROR: Unexpected token ';' [Ln 4, Col 32]\n```\n      allow read, write: if true;;\n                               ^\n```",
+  "rawIssues": [
+    {
+      "sourcePosition": {
+        "line": 4,
+        "column": 32,
+        "currentOffset": 105,
+        "endOffset": 106
+      },

+  "looker-get-looks" searches for saved Looks in a Looker

+
+## About
+
+The `looker-get-looks` tool searches for a saved Look by
+name or description.
+
+It's compatible with the following sources:
+
+- [looker](../sources/looker.md)
+
+`looker-get-looks` takes four parameters, the `title`, `desc`, `limit`
+and `offset`.
+
+Title and description use SQL style wildcards and are case insensitive.
+
+Limit and offset are used to page through a larger set of matches and
+default to 100 and 0.
+
+## Example
+
+```yaml
+tools:
+    get_looks:
+        kind: looker-get-looks
+        source: looker-source
+        description: |
+          get_looks Tool
+
+          This tool is used to search for saved looks in a Looker instance.
+          String search params use case-insensitive matching. String search
+          params can contain % and '_' as SQL LIKE pattern match wildcard
+          expressions. example="dan%" will match "danger" and "Danzig" but
+          not "David" example="D_m%" will match "Damage" and "dump".
+
+          Most search params can accept "IS NULL" and "NOT NULL" as special
+          expressions to match or exclude (respectively) rows where the
+          column is null.
+
+          The limit and offset are used to paginate the results.
+
+          The result of the get_looks tool is a list of json objects.

+  A "neo4j-execute-cypher" tool executes any arbitrary Cypher statement against a Neo4j
+  database.

+---
+
+## About
+
+A `neo4j-execute-cypher` tool executes an arbitrary Cypher query provided as a string parameter against a Neo4j database. It's designed to be a flexible tool for interacting with the database when a pre-defined query is not sufficient. This tool is compatible with any of the following sources:
+
+- [neo4j](../sources/neo4j.md)
+
+For security, the tool can be configured to be read-only. If the `readOnly` flag is set to `true`, the tool will analyze the incoming Cypher query and reject any write operations (like `CREATE`, `MERGE`, `DELETE`, etc.) before execution.
+
+The Cypher query uses standard [Neo4j Cypher](https://neo4j.com/docs/cypher-manual/current/queries/) syntax and supports all Cypher features, including pattern matching, filtering, and aggregation.
+
+`neo4j-execute-cypher` takes one input parameter `cypher` and run the cypher query against the `source`.
+
+> **Note:** This tool is intended for developer assistant workflows with
+> human-in-the-loop and shouldn't be used for production agents.
+
+## Example
+
+```yaml
+tools:
+  query_neo4j:
+    kind: neo4j-execute-cypher
+    source: my-neo4j-prod-db
+    readOnly: true
+    description: |
+      Use this tool to execute a Cypher query against the production database.
+      Only read-only queries are allowed.
+      Takes a single 'cypher' parameter containing the full query string.
+      Example:
+      {{
+          "cypher": "MATCH (m:Movie {title: 'The Matrix'}) RETURN m.released"
+      }}
+```

+  How to get started running Toolbox with Gemini-CLI and Looker as the source.
+---
+
+## Overview
+
+[Model Context Protocol](https://modelcontextprotocol.io) is an open protocol
+that standardizes how applications provide context to LLMs. Check out this page
+on how to [connect to Toolbox via MCP](../../how-to/connect_via_mcp.md).
+
+## Step 1: Get a Looker Client ID and Client Secret
+
+The Looker Client ID and Client Secret can be obtained from the Users page of
+your Looker instance. Refer to the documentation
+[here](https://cloud.google.com/looker/docs/api-auth#authentication_with_an_sdk).
+You may need to ask an administrator to get the Client ID and Client Secret
+for you.
+
+## Step 2: Install and configure Toolbox
+
+In this section, we will download Toolbox and run the Toolbox server.
+
+1. Download the latest version of Toolbox as a binary:
+
+    {{< notice tip >}}
+   Select the
+   [correct binary](https://github.com/googleapis/genai-toolbox/releases)
+   corresponding to your OS and CPU architecture.
+    {{< /notice >}}
+    <!-- {x-release-please-start-version} -->
+    ```bash
+    export OS="linux/amd64" # one of linux/amd64, darwin/arm64, darwin/amd64, or windows/amd64
+    curl -O https://storage.googleapis.com/genai-toolbox/v0.10.0/$OS/toolbox
+    ```
+    <!-- {x-release-please-end} -->
+
+1. Make the binary executable:
+
+    ```bash
+    chmod +x toolbox
+    ```
+
+1. Edit the file `~/.gemini/settings.json` and add the following
+   to the list of mcpServers. Use the Client Id and Client Secret
+   you obtained earlier.
+
+   ```json
+      "mcpServers": {
+        "looker-toolbox": {
+          "command": "/path/to/toolbox",
+          "args": [
+            "--stdio",
+            "--prebuilt",
+            "looker"
+          ],
+          "env": {
+            "LOOKER_BASE_URL": "https://looker.example.com",
+            "LOOKER_CLIENT_ID": "",
+            "LOOKER_CLIENT_SECRET": "",
+            "LOOKER_VERIFY_SSL": "true"
+          }
+        }
+      }
+   ```
+
+   In some instances you may need to append `:19999` to
+   the LOOKER_BASE_URL.
+
+## Step 3: Start Gemini-CLI
+
+1. Run Gemini-CLI:
+
+    ```bash
+    npx https://github.com/google-gemini/gemini-cli
+    ```
+
+1. Type `y` when it asks to download.
+
+1. Log into Gemini-CLI
+
+1. Enter the command `/mcp` and you should see a list of
+   available tools like
+
+   ```
+    ℹ Configured MCP servers:
+
+      🟢 looker-toolbox - Ready (10 tools)
+        - looker-toolbox__get_models
+        - looker-toolbox__query
+        - looker-toolbox__get_looks
+        - looker-toolbox__get_measures
+        - looker-toolbox__get_filters
+        - looker-toolbox__get_parameters
+        - looker-toolbox__get_explores
+        - looker-toolbox__query_sql
+        - looker-toolbox__get_dimensions
+        - looker-toolbox__run_look
+    ```
+1. Start exploring your Looker instance with commands like
+   `Find an explore to see orders` or `show me my current
+   inventory broken down by item category`.
+
+1. Gemini will prompt you for your approval before using
+   a tool. You can approve all the tools.

+          model, explore, and fields list must be specified. Pivots,
+          filters and sorts are optional.
+
+          The model can be found from the get_models tool. The explore
+          can be found from the get_explores tool passing in the model.
+          The fields can be found from the get_dimensions, get_measures,
+          get_filters, and get_parameters tools, passing in the model
+          and the explore.
+
+          Provide a model_id and explore_name, then a list
+          of fields. Optionally a list of pivots can be provided.
+          The pivots must also be included in the fields list.
+
+          Filters are provided as a map of {"field.id": "condition",
+          "field.id2": "condition2", ...}. Do not put the field.id in
+          quotes. Filter expressions can be found at
+          https://cloud.google.com/looker/docs/filter-expressions.
+
+          Sorts can be specified like [ "field.id desc 0" ].
+
+          An optional row limit can be added. If not provided the limit
+          will default to 500. "-1" can be specified for unlimited.
+
+          An optional query timezone can be added. The query_timezone to
+          will default to that of the workstation where this MCP server
