MCP Server for AI Documentation

Access Chainguard documentation through MCP for AI assistants and automation
  4 min read

Overview

The Chainguard AI Documentation MCP (Model Context Protocol) server enables AI assistants and automation tools to interact with Chainguard’s complete documentation library through a standardized protocol. This provides efficient, searchable access to container image docs, security guides, and tool references without loading entire documentation bundles into context.

What is MCP?

Model Context Protocol (MCP) is an open protocol that standardizes how AI applications access external data and tools. MCP servers expose structured data and capabilities that AI assistants can query and use to provide more accurate, context-aware responses.

Why Use the MCP Server?

Efficient Context Usage

  • Only retrieve relevant documentation sections
  • Avoid loading 2.8 MB of docs into every prompt
  • Search and filter content dynamically

Better for Agents

  • Programmatic access to documentation
  • Structured queries (get specific image docs, search CVEs, etc.)
  • Perfect for automated workflows and CI/CD

IDE Integration

  • Works with Claude Desktop, Cursor, and other MCP-compatible tools
  • Access Chainguard docs while coding
  • No manual copy/paste needed

Getting Started

Prerequisites

  • Docker installed
  • MCP-compatible client (Claude Desktop, Cursor, etc.)

Pull the Container 

docker pull ghcr.io/chainguard-dev/ai-docs:latest

Run the MCP Server 

docker run --rm -i ghcr.io/chainguard-dev/ai-docs:latest serve-mcp

The server runs in stdio mode and communicates via standard input/output, making it compatible with MCP clients.

Claude Desktop Configuration

To use this MCP server with Claude Desktop, add it to your configuration file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "chainguard-docs": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "ghcr.io/chainguard-dev/ai-docs:latest",
        "serve-mcp"
      ]
    }
  }
}

After adding this configuration, restart Claude Desktop. The Chainguard documentation tools will be available in your conversations.

Available Tools

The MCP server provides these tools for querying Chainguard documentation:

search_docs

Search across all Chainguard documentation for relevant content.

Parameters:

  • query (string, required): Search query
  • max_results (integer, optional): Maximum results to return (default: 5)

Example prompts:

  • “Search Chainguard docs for python CVE management”
  • “Find information about FIPS compliance”
  • “Search for nginx configuration examples”

get_image_docs

Get documentation for a specific Chainguard container image.

Parameters:

  • image_name (string, required): Image name (e.g., “python”, “node”, “nginx”)

Example prompts:

  • “Show me the Python image documentation”
  • “Get docs for the nginx image”
  • “What’s in the node image?”

list_images

List all available Chainguard container images.

Example prompts:

  • “List all Chainguard images”
  • “What images are available?”
  • “Show me the image catalog”

get_security_docs

Get security-related documentation including CVE management, SBOMs, and signing.

Example prompts:

  • “How does Chainguard handle CVEs?”
  • “Show me security documentation”
  • “Explain SBOM generation”

get_tool_docs

Get documentation for Chainguard tools and ecosystem components.

Parameters:

  • tool_name (string, required): Tool name: wolfi, apko, melange, or chainctl

Example prompts:

  • “Show me wolfi documentation”
  • “How do I use apko?”
  • “Explain melange”

Example Usage

Once configured with Claude Desktop:

You: Search for python image security best practices

Claude: [Uses search_docs tool]
Based on the Chainguard documentation, here are Python image security best practices:
...
You: Show me the nginx image documentation

Claude: [Uses get_image_docs tool]
Here's the complete documentation for the Chainguard nginx image:
...

Alternative: Static Documentation

If you don’t need MCP server functionality, you can extract the documentation as a single markdown file:

docker run --rm -v $(pwd):/output \
  ghcr.io/chainguard-dev/ai-docs:latest extract /output

See the Developer Resources page for more details on static extraction.

Security Features

Following Chainguard’s security-first approach:

  • Minimal Image: Built on cgr.dev/chainguard/wolfi-base
  • Zero CVEs: Regularly updated to maintain zero known vulnerabilities
  • Non-root: Runs as non-root user
  • Signed: Container images are signed with Cosign
  • Transparent: Full SBOM and provenance available

Troubleshooting

Server Not Appearing in Claude Desktop

  1. Check that the configuration file path is correct
  2. Ensure Docker is running
  3. Restart Claude Desktop after configuration changes
  4. Check Claude Desktop logs for error messages

Connection Issues 

# Test the server manually
docker run --rm -i ghcr.io/chainguard-dev/ai-docs:latest serve-mcp

The server should start and display startup messages.

Documentation Out of Date

Pull the latest container image:

docker pull ghcr.io/chainguard-dev/ai-docs:latest

The documentation is automatically updated weekly.
