chore: add preprocessing function to convert tools file

## Description

This pull request adds a new tool, cloud-sql-create-backup, which
enables taking a backup on a Cloud SQL instance from the toolbox using
the Cloud SQL Admin API. The tool supports optionally supplying a
location or description for the backup.

+## Guidelines for Pull Requests
+
+1. Please keep your PR small for more thorough review and easier updates. In case of regression, it also allows us to roll back a single feature instead of multiple ones.
+1. For non-trivial changes, consider opening an issue and discussing it with the code owners first.
+1. Provide a good PR description as a record of what change is being made and why it was made. Link to a GitHub issue if it exists.
+1. Make sure your code is thoroughly tested with unit tests and integration tests. Remember to clean up the test instances properly in your code to avoid memory leaks.

-# Cloud Spanner Admin MCP Server
-
-The Cloud Spanner Admin Model Context Protocol (MCP) Server gives AI-powered development tools the ability to manage your Google Cloud Spanner infrastructure. It supports creating instances.
-
-## Features
-
-An editor configured to use the Cloud Spanner Admin MCP server can use its AI capabilities to help you:
-
-- **Provision & Manage Infrastructure** - Create Cloud Spanner instances
-
-## Prerequisites
-
-*   [Node.js](https://nodejs.org/) installed.
-*   A Google Cloud project with the **Cloud Spanner Admin API** enabled.
-*   Ensure [Application Default Credentials](https://cloud.google.com/docs/authentication/gcloud) are available in your environment.
-*   IAM Permissions:
-    *   Cloud Spanner Admin (`roles/spanner.admin`)
-
-## Install & Configuration
-
-In the Antigravity MCP Store, click the "Install" button.
-
-You'll now be able to see all enabled tools in the "Tools" tab.
-
-> [!NOTE]
-> If you encounter issues with Windows Defender blocking the execution, you may need to configure an allowlist. See [Configure exclusions for Microsoft Defender Antivirus](https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/configure-exclusions-microsoft-defender-antivirus?view=o365-worldwide) for more details.
-
-## Usage
-
-Once configured, the MCP server will automatically provide Cloud Spanner Admin capabilities to your AI assistant. You can:
-
-   * "Create a new Spanner instance named 'my-spanner-instance' in the 'my-gcp-project' project with config 'regional-us-central1', edition 'ENTERPRISE', and 1 node."
-
-## Server Capabilities
-
-The Cloud Spanner Admin MCP server provides the following tools:
-
-| Tool Name         | Description                      |
-|:------------------|:---------------------------------|
-| `create_instance` | Create a Cloud Spanner instance. |
-
-## Custom MCP Server Configuration
-
-Add the following configuration to your MCP client (e.g., `settings.json` for Gemini CLI, `mcp_config.json` for Antigravity):
-
-```json
-{
-  "mcpServers": {
-    "spanner-admin": {
-      "command": "npx",
-      "args": ["-y", "@toolbox-sdk/server", "--prebuilt", "spanner-admin", "--stdio"]
-    }
-  }
-}
-```
-

-alias: [/resources/sources/spanner-admin]
----
-
-## About
-
-The `spanner-admin` source provides a client to interact with the [Google
-Cloud Spanner Admin API](https://cloud.google.com/spanner/docs/reference/rpc/google.spanner.admin.instance.v1). This
-allows tools to perform administrative tasks on Spanner instances, such as
-creating instances.
-
-Authentication can be handled in two ways:
-
-1.  **Application Default Credentials (ADC):** By default, the source uses ADC
-    to authenticate with the API.
-2.  **Client-side OAuth:** If `useClientOAuth` is set to `true`, the source will
-    expect an OAuth 2.0 access token to be provided by the client (e.g., a web
-    browser) for each request.
-
-## Example
-
-```yaml
-sources:
-    my-spanner-admin:
-        kind: spanner-admin
-
-    my-oauth-spanner-admin:
-        kind: spanner-admin
-        useClientOAuth: true

+title: "Quickstart (MCP with Neo4j)"
+type: docs
+weight: 1
+description: >
+  How to get started running Toolbox with MCP Inspector and Neo4j 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: Set up your Neo4j Database and Data
+
+In this section, you'll set up a database and populate it with sample data for a movies-related agent. This guide assumes you have a running Neo4j instance, either locally or in the cloud.
+
+. **Populate the database with data.**
+To make this quickstart straightforward, we'll use the built-in Movies dataset available in Neo4j.
+
+. In your Neo4j Browser, run the following command to create and populate the database:
++
+```cypher
+:play movies
+````
+
+. Follow the instructions to load the data. This will create a graph with `Movie`, `Person`, and `Actor` nodes and their relationships.
+
+
+## Step 2: Install and configure Toolbox
+
+In this section, we will install the MCP Toolbox, configure our tools in a `tools.yaml` file, and then run the Toolbox server.
+
+. **Install the Toolbox binary.**
+The simplest way to get started is to download the latest binary for your operating system.
+
+. Download the latest version of Toolbox as a binary:
+\+
+
+```bash
+export OS="linux/amd64" # one of linux/amd64, darwin/arm64, darwin/amd64, or windows/amd64
+curl -O [https://storage.googleapis.com/genai-toolbox/v0.16.0/$OS/toolbox](https://storage.googleapis.com/genai-toolbox/v0.16.0/$OS/toolbox)
+```
+
+  + 
+. Make the binary executable:
+\+
+
+```bash
+chmod +x toolbox
+```
+
+. **Create the `tools.yaml` file.**
+This file defines your Neo4j source and the specific tools that will be exposed to your AI agent.
+\+
+{{\< notice tip \>}}
+Authentication for the Neo4j source uses standard username and password fields. For production use, it is highly recommended to use environment variables for sensitive information like passwords.
+{{\< /notice \>}}
+\+
+Write the following into a `tools.yaml` file:
+\+
+
+```yaml
+sources:
+  my-neo4j-source:
+    kind: neo4j
+    uri: bolt://localhost:7687
+    user: neo4j
+    password: my-password # Replace with your actual password
+
+tools:
+  search-movies-by-actor:
+    kind: neo4j-cypher
+    source: my-neo4j-source
+    description: "Searches for movies an actor has appeared in based on their name. Useful for questions like 'What movies has Tom Hanks been in?'"
+    parameters:
+      - name: actor_name
+        type: string
+        description: The full name of the actor to search for.
+    statement: |
+      MATCH (p:Person {name: $actor_name}) -[:ACTED_IN]-> (m:Movie)
+      RETURN m.title AS title, m.year AS year, m.genre AS genre
+  
+  get-actor-for-movie:
+    kind: neo4j-cypher
+    source: my-neo4j-source
+    description: "Finds the actors who starred in a specific movie. Useful for questions like 'Who acted in Inception?'"
+    parameters:
+      - name: movie_title
+        type: string
+        description: The exact title of the movie.
+    statement: |
+      MATCH (p:Person) -[:ACTED_IN]-> (m:Movie {title: $movie_title})
+      RETURN p.name AS actor
+```
+
+. **Start the Toolbox server.**
+Run the Toolbox server, pointing to the `tools.yaml` file you created earlier.
+\+
+
+```bash
+./toolbox --tools-file "tools.yaml"
+```
+
+## Step 3: Connect to MCP Inspector
+
+. **Run the MCP Inspector:**
+\+
+
+```bash
+npx @modelcontextprotocol/inspector
+```
+
+. Type `y` when it asks to install the inspector package.
+. It should show the following when the MCP Inspector is up and running (please take note of `<YOUR_SESSION_TOKEN>`):
+\+
+
+```bash
+Starting MCP inspector...
+⚙️ Proxy server listening on localhost:6277
+🔑 Session token: <YOUR_SESSION_TOKEN>
+    Use this token to authenticate requests or set DANGEROUSLY_OMIT_AUTH=true to disable auth
+
+🚀 MCP Inspector is up and running at:
+    http://localhost:6274/?MCP_PROXY_AUTH_TOKEN=<YOUR_SESSION_TOKEN>
+```
+
+1. Open the above link in your browser.
+
+1. For `Transport Type`, select `Streamable HTTP`.
+
+1. For `URL`, type in `http://127.0.0.1:5000/mcp`.
+
+1. For `Configuration` -\> `Proxy Session Token`, make sure `<YOUR_SESSION_TOKEN>` is present.
+
+1. Click `Connect`.
+
+1. Select `List Tools`, you will see a list of tools configured in `tools.yaml`.
+
+1. Test out your tools here\!
