Ook Cite MCP Server

Give MCP-capable tools the ability to validate DOIs, format citations, manage bibliography collections, and catch fabricated references. Returns citation metadata only -- not PDFs or full-text articles. Works with clients that support MCP servers over standard input and output. Its 37 documented tools cover collection, batch, orcid, check. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Ook Cite

before you install - you'll need

Set OOKCITE_API_KEY_COMMAND, OOKCITE_CONTRACT_KEY before connecting. OOKCITE_API_KEY is optional or environment-specific per the README.

Claude Code

claude mcp add turtletech-ehf-ookcite-mcp -- npx -y @turtletech/ookcite-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "turtletech-ehf-ookcite-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@turtletech/ookcite-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @turtletech/ookcite-mcp - the @turtletech scope differs from the repo owner (turtletech-ehf); confirm it's the project's official package

registry namespace io.github.TurtleTech-ehf is GitHub-verified and matches the repo owner

03 · What Ook Cite can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can check if a DOI exists (anti-hallucination), find a paper from messy citation text, resolve many citation strings in one request (max 50), and format a DOI in any of 2900+ CSL styles.
