Oxford Ledge MCP Server

Last updated: 2026-09-26

Version: 3.8.0 (gov-public-data-only surface; CUSIP + third-party-FRED carve-outs)

<!-- mcp-name: com.oxfordledge/oxford-ledge -->

Ask your assistant; it reads the public record. This package lets Claude, Codex, Cursor or any client that speaks the Model Context Protocol look things up in SEC filings and fundamentals, 13F holdings, insider trades, BDC loan books, and Treasury, FRED, FDIC, USAspending, USPTO and CFTC data, with the source named on the answer.

Install: pip install oxford-ledge-mcp (Python 3.9 or later, no third-party dependencies). Connect: step-by-step setup for each client, and a free API key, at oxfordledge.com/mcp.

Free on every Oxford Ledge plan, and a few tools run with no account at all (see Standalone mode below). The release notes come next; what the tools cover, the three modes, the tool list and the data terms follow them.

Release notes

This is 3.8.0. It also carries everything in the 3.7.2 cut described next, which was never published on its own -- upgrading from 3.7.1 gets both. Changed: every tool description is now a short card of at most 1,300 characters -- what the tool returns, its key arguments, its source and the one caveat to know before calling -- so a connected session spends far fewer tokens before its first call (the 29 descriptions went from about 70,900 to about 23,700 characters). The caveats that used to live in the descriptions now ride each response in a toolnotes list, placed near the head of the payload; licence, redistribution and refusal notices stay verbatim in the descriptions. Changed: responsesize.overbudget now judges the data without toolnotes, while chars still reports the whole payload. No tool, argument or data key is renamed or removed.

Shortened. The full README is on GitHub.
