How to Set Up and Use PAIML Agent Toolkit
The PAIML MCP Agent Toolkit (pmat) is a Rust-based MCP server and CLI from Pragmatic AI Labs that makes AI-assisted coding more deterministic by providing rigorous code analysis tools: complexity scoring, technical debt grading, semantic code search, mutation testing, and quality gates. It exposes over 20 tools to MCP clients like Claude Code, enabling agents to measure and enforce code quality rather than relying on subjective assessment, and supports 20+ programming languages including Rust, Python, TypeScript, Go, Java, and C/C++.
Prerequisites
- Rust toolchain installed (for building from source) or Cargo available
- An MCP-compatible client such as Claude Code, Cline, or Claude Desktop
- MCP_VERSION environment variable set to 2024-11-05 for server mode
- Optional: .pmat.yaml for project compliance configuration
Install pmat via Cargo
Install the pmat binary from crates.io. This is the recommended method and works on macOS, Linux, and Windows.
cargo install pmatVerify the installation
Confirm pmat is installed correctly and check available commands.
pmat --version
pmat --helpRun a quick code quality analysis
Test pmat on your codebase before connecting it as an MCP server. The repo-score command gives a holistic health assessment.
pmat repo-score .Configure the MCP server environment variable
pmat starts in MCP server mode (stdio) when the MCP_VERSION environment variable is set. Add this to your MCP client configuration.
export MCP_VERSION=2024-11-05
pmat # launches as MCP stdio serverAdd pmat to your MCP client configuration
Edit your claude_desktop_config.json to add pmat as an MCP server with the required MCP_VERSION environment variable. Once connected, Claude can call its 20+ tools for code analysis, complexity scoring, semantic search, and quality verification.

}Prompts to try
Use these prompts with Claude after connecting the PAIML MCP Agent Toolkit to analyze and improve code quality.
- "Analyze the technical debt of this repository and give me an A-F grade with the 6 orthogonal metrics."
- "Search the codebase for all implementations related to cache invalidation and explain how they work."
- "Run the complexity analysis on the src/ directory and identify the top 5 most complex functions."
- "Generate an AI-optimized context summary of this entire codebase for use in a new Claude conversation."
- "Check if this project passes all quality gates defined in .pmat-gates.toml."Troubleshooting PAIML Agent Toolkit
pmat starts but immediately exits without entering MCP server mode
Ensure MCP_VERSION=2024-11-05 is set in the environment variable section of your MCP client config. Without it, pmat defaults to CLI mode and exits.
cargo install pmat fails with compilation errors
Ensure your Rust toolchain is up to date with 'rustup update stable'. pmat is written in Rust and requires a recent stable toolchain. Also confirm you have the build-essential tools (gcc/clang) on Linux.
pmat analyze or pmat context returns errors for certain file types
pmat supports 20+ languages but not all file types. Check the supported language list in the documentation. For unsupported files, exclude them using .gitignore-style patterns or the --exclude flag.
