mcp

Overview ¶

Package mcp implements a minimal stdio JSON-RPC 2.0 server that exposes read-only db-catalyst tools to AI agents via the Model Context Protocol (MCP).

Framing ¶

The server uses newline-delimited JSON: each request and each response is a single JSON object followed by a newline character ('\n'). There is no Content-Length header framing. Clients must send one complete JSON object per line and must read complete lines from the server.

Tools ¶

• schema_list – returns a summary of all tables and their columns.
• query_check – validates + types a single SQL statement using the static analyzer and the SQLite verify oracle; returns columns and diagnostics.
• query_preview – returns a preview of the generated Go method signature and row struct derived from a SQL statement.
