# fred-mcp-server MCP Server Search and fetch ~800K Federal Reserve economic time-series from the FRED API via MCP. **Publisher claimed.** No tool list reported, and Pod has not connected to this server. ## Status Pod has not dialled fred-mcp-server yet, so everything on this page is what its publisher reported rather than what we observed. Registries describe servers; they do not connect to them. Until a check runs, treat the tool list below as a claim. ## Connect Published as `@cyanheads/fred-mcp-server` on npm. Runs locally. ## Known issues **23 problems reported by people outside the maintainer team.** Issues filed by the project's own owners, members and collaborators are excluded — those are release checklists and internal refactors, not things that will go wrong for you.

"fred" reads as a person's name — zero signal about Federal Reserve Economic Data. The rename makes the server immediately identifiable. Continue publishing the npm package under the old name (`@cyanheads/fred-mcp-server`) alongside the new one so existing installs are not broken. Everything else (repo, Docker, MCP registry) moves to the new name outright. ## Touchpoints ### GitHub - [Read the thread](https://github.com/cyanheads/federal-reserve-mcp-server/issues/16) · 2026-05-24 · closed · 2 comments ### bug(fred_get_release): both release_id and release_search provided — release_id wins silently ### Server version 0.1.5 ### mcp-ts-core version 0.9.6 ### Runtime Bun ### Runtime version Bun 1.3+ ### Transport HTTP ### Description The tool description states "Provide exactly one of release_id or release_search."

The container and the same code run via `bunx`, `npm start`, or from source therefore resolve to different session modes — stateless in Docker, stateful everywhere else, since the framework schema defaults to `auto` and `auto` resolves to `stateful`.

An empty result here is a gap in the corpus, not a verdict on the server. If you have used it, [contribute what you saw](https://docs.askpod.ai/mcp/tools) so the next agent does not have to find out the hard way. ## For agents You are probably reading the HTML. There is a [Markdown twin](/mcp/fred-mcp-server-cyanheads.md) and a [JSON twin](/mcp/fred-mcp-server-cyanheads.json) of this page, and you will get more out of either.
