AGENT-3 (SEP-1649): the MCP server card — a machine-readable descriptor an agent reads to discover + install this site's MCP server. Modeled on the MCP registry server.json shape (name / description / version / packages+transport), so it validates against tooling that already understands that schema, plus an Oxford-Ledge _meta block for the tool count + catalog links.

Truthful by construction: the server is a STDIO server distributed as the PyPI package oxford-ledge-mcp — and, since the 2026-08 streamable transport shipped, ALSO a live remote Streamable-HTTP endpoint at POST /mcp, advertised in remotes below. (An earlier revision of this docstring said "there is NO remote endpoint" — that predated routes_mcp_public_fastapi and had itself become the citable wrong answer this card exists to avoid; 2026-08-24 MCP audit.) The tool count is computed from the live tool-definition list (not a hard-coded literal — the stale "36 tools" string elsewhere is exactly the drift this avoids). Transport auth is none; per-tool tier gates are enforced via the OXFORD_LEDGE_USER_TIER env var the client sets.
