Zed openfda mcp server openfda_dataframe_describe

How to: Zed openfda mcp server openfda_dataframe_describe

client:Zed transport:streamable-http tool:openfda_dataframe_describe

Add openfda mcp server to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "openfda-mcp-server": {
      "url": "https://openfda.caseyjhand.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something openfda_dataframe_describe does. Zed lists the server's tools on connect and calls openfda_dataframe_describe itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that openfda mcp server's identifier in your config matches the one above exactly.

Merge this into your existing settings object — do not replace the file. Zed docs

Set these first

openfda mcp server will not start until these are set, so openfda_dataframe_describe never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
