Pact Tooling MCP

Provides AI agents with safe, auditable access to the Pact 5 development loop on Kadena Chainweb. It enables REPL test runs, critical-trap scanning, gas estimation, interface diffing, and format checks. The server operates behind a strict security baseline where no tool ever touches a private key, allowing integration with clients like Claude, Cursor, and VS Code.
