MAID Runner MCP

Model Context Protocol server for MAID Runner validation tools.

MAID Runner MCP exposes MAID Runner validation capabilities via the Model Context Protocol (MCP), enabling seamless integration with AI development tools like Claude Code, Aider, and custom AI agents.

What Is This?

MAID Runner MCP is a bridge between AI agents and MAID Runner's validation framework. It provides:

• MCP Tools: Programmatic access to maid validate, maid snapshot, maid test, and other commands
• MCP Resources: Access to manifests, schemas, validation results, and system architecture
• MCP Prompts: Workflow guidance for AI agents through MAID methodology phases

Think of it as an API layer that lets AI agents interact with MAID Runner using standardized MCP protocol instead of subprocess calls.

Status

🚧 Alpha Release - Under active development.

This is part of the MAID ecosystem and follows the MAID methodology itself (self-dogfooding).

Quick Start

Installation

# Install from PyPI
pip install maid-runner-mcp

# Or with uv
uv pip install maid-runner-mcp

Running the Server

# Start MCP server (stdio transport)
maid-runner-mcp

# Or with uv
uv run maid-runner-mcp

Integration with Claude Code

Add to your .claude/mcp.json:

{
  "mcpServers": {
    "maid-runner": {
      "command": "uv",
      "args": ["run", "maid-runner-mcp"],
      "env": {
        "MAID_MANIFEST_DIR": "manifests"
      }
    }
  }
}

Now Claude Code can:

• Validate manifests via maid_validate tool
• Generate snapshots via maid_snapshot tool
• Access manifest content via manifest:// resources
• Get workflow guidance via prompts

How It Relates to MAID Runner

Component	Role	What It Does
MAID Runner	Validation framework	CLI tool for validating MAID manifests
MAID Runner MCP	MCP interface	Exposes MAID Runner to AI agents via MCP

MAID Runner MCP doesn't replace the CLI—it complements it:

• CLI (maid): For humans and shell scripts
• MCP (maid-runner-mcp): For AI agents and programmatic access

Both use the same underlying validation logic.

Use Cases

1. AI-Assisted Development

AI agents can validate code as they generate it:

# AI agent workflow
result = await session.call_tool("maid_validate", {
    "manifest_path": "manifests/task-013.manifest.json",
    "use_manifest_chain": true
})

if not result["success"]:
    # Fix issues based on errors
    ...

2. Architecture Exploration

AI agents can understand system architecture:

# Get system snapshot
snapshot = await session.read_resource("snapshot://system")

# Query knowledge graph
results = await session.read_resource(
    "graph://query?type=class&name=EmailValidator"
)

3. Workflow Automation

Custom agents can automate MAID workflow:

# Get planning guidance
prompt = await session.get_prompt("plan-task", {
    "goal": "Add email validation"
})

# Follow prompt to create manifest
...

Development

Setup

# Clone repository
git clone https://github.com/mamertofabian/maid-runner-mcp
cd maid-runner-mcp

# Install dependencies
uv pip install -e ".[dev]"

# Run tests
pytest tests/ -v

Makefile Commands

make install      # Install package
make test         # Run tests
make lint         # Check code style
make format       # Format code
make validate     # Validate MAID manifests

MAID Compliance

This project follows the MAID methodology itself:

• All changes have manifests in manifests/
• All features have behavioral tests in tests/
• Validation enforced via maid validate --use-manifest-chain
