@diegomendez40 should we mark it as experimental?

description: >-
A Model Context Protocol server for generating and executing AQL queries using AI assistants like Claude and Cursor IDE
---
The ArangoDB MCP Server is a focused [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) implementation that enables AI assistants to generate and execute AQL queries based on natural language questions. It includes lightweight schema discovery and manuals to ground queries in actual database structure.

## Features

**AQL Generation & Execution:**
- Generate AQL grounded in actual database structure
- Execute AQL with optional bind variables and target database

**Manuals for Guidance:**
- AQL reference and optimization guides built-in
- Context-aware query generation

**Lightweight Schema Discovery:**
- List collections within accessible databases
- Sample documents via simple filters to learn fields

## What You Can Do

The server is purpose-built for safe, read-focused AQL operations:
- Execute AQL queries with optional bind variables and target database
- Access built-in manuals for syntax and optimization guidance
- Discover database schemas and collection structures
- Sample documents to understand field structures

The following are not included:
- Graph/view/index/analyzer management tools
- Destructive admin operations (create/delete databases or collections)

## Installation

The ArangoDB MCP Server is available as a Docker image on Docker Hub: [arangodb/mcp-arangodb](https://hub.docker.com/r/arangodb/mcp-arangodb)

See the Docker Hub page for installation and usage instructions.

## Available Tools

The MCP server exposes four main tools that AI assistants can use to interact with your ArangoDB database.

### `get-aql-manual`

Retrieves built-in documentation for AQL syntax and optimization.

**Parameters:**
- `manual_name` (required): Either `aql_ref` or `optimization`.

**Use when:** You need reference documentation for writing AQL queries.

### `fetch-schemas`

Lists all collections in a database (non-system collections only).

**Parameters:**
- `database_name` (optional): Target database. Uses configured default if not specified.

**Use when:** You need to discover what collections exist in your database.

### `read-documents-with-filter`

Samples documents from a collection using simple equality filters.

**Parameters:**
- `collection_name` (required): Name of the collection to query.
- `filters` (required): Filter conditions as key-value pairs.
- `limit` (optional, default: 100): Maximum documents to return.
- `skip` (optional, default: 0): Number of documents to skip (pagination).

**Use when:** You want to explore document structure or find specific documents by exact field matches.

### `execute-aql-query`

Executes AQL queries with optional bind variables.

**Parameters:**
- `aql_query` (required): The AQL query to execute.
- `bind_vars` (optional): Bind variables for parameterized queries.
- `database_name` (optional): Target database.

**Use when:** You need to run complex queries, aggregations, or graph traversals.

## Workflow

When working with the MCP server, AI assistants typically follow this pattern:

1. **Discover**: Call `fetch-schemas()` to understand available collections.
2. **Explore**: Use `read-documents-with-filter()` to see document structures.
3. **Reference**: Call `get-aql-manual()` if complex query syntax is needed.
4. **Execute**: Run queries with `execute-aql-query()` using bind variables for safety.

## Practical Examples

**Example 1: Exploring Your Database**

*Prompt:* "Show me all collections in the database"

The AI will call `fetch-schemas()` and display the available collections with their types and document counts.

**Example 2: Finding Specific Records**

*Prompt:* "Find all active users who are verified"

The AI will:
1. Confirm the `users` collection exists with `fetch-schemas()`
2. Sample the structure with `read-documents-with-filter()`
3. Generate and execute an AQL query:
```aql
FOR user IN users
FILTER user.status == "active" AND user.verified == true
RETURN user
```

**Example 3: Complex Graph Traversal**

*Prompt:* "Find all friends of friends for user 'john' up to 3 levels deep"

The AI will:
1. Retrieve the AQL reference manual for graph traversal syntax
2. Identify edge collections using `fetch-schemas()`
3. Generate an optimized graph query:
```aql
FOR v, e, p IN 1..3 OUTBOUND 'users/john' friends
RETURN DISTINCT v
```
4. Execute with appropriate bind variables for safety

**Example 4: Data Analysis**

*Prompt:* "What's the average age of users by country?"

The AI will generate and execute an aggregation query:
```aql
FOR user IN users
COLLECT country = user.address.country
AGGREGATE avgAge = AVG(user.age)
RETURN { country, avgAge }
```
