ParityDiff MCP
Node.js 24 stdio server for captured ParityDiff contract evidence. The standalone
download supports the stdio server and evidence checks. The npm package includes
the TypeScript parser required for local repository matching.
Run node tools/mcp/server.mjs. Setup is published at /mcp; the website build
copies the same source to /downloads/paritydiff-mcp.mjs.
Version 0.1.0 is available on npm. The next release is prepared from GitHub.
After version 0.1.1 is published, use npx --yes @paritydiff/mcp@0.1.1 as the stdio server command,
and run npx @paritydiff/mcp@0.1.1 login to link a workspace.
Tools list public APIs, captured operation previews and SDK package names, release metadata, and classified changes. The IDE assistant can inspect a native SDK or HTTP call locally and use its method/path to filter recorded changes. The public and private evidence tools do not read local files or invoke inference. The separately approved migration tools use confirmed workspace review sessions. The IDE's own inference policies still apply.
