@mcpolyglot/core

The runtime that powers mcpolyglot. Defines the Connector interface, the McpolyglotServer, the transport abstraction, and the non-bypassable security pipeline that wraps every tool call.

You usually don't depend on this directly — install @mcpolyglot/cli instead. Use this package when you want to embed mcpolyglot in your own host or write a custom connector.

What's in here

• McpolyglotServer — wires connectors, security hooks, and a transport into an MCP-compliant server. Every tool call goes through the same pipeline:

  scope check → rate limit → timeout → handler → redact → size cap → wrap → audit
  

  Connectors can't opt out.
• Connector — the interface a data-source adapter implements (init, close, health, listPrimitiveTools, optional diagnose).
• Transport — minimal contract; ships with StdioTransport and StreamableHttpTransport.
• ToolDefinition — { name, description, inputSchema (zod), scopes, readOnly, handler }.
