-## 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.

-type: docs

-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\!
