@jambonz/mcp-schema-server

MCP server that provides jambonz verb schemas and documentation to AI agents via the Model Context Protocol.

How It Works

This server exposes the schemas and developer guide from the @jambonz/schema package as MCP tools. AI coding agents can query verb definitions, component types, callback payloads, and the full developer guide without needing local access to the schema files.
