Validate DOIs against a real citation database, format references in 2900+ CSL styles (APA, IEEE, Chicago, Nature, etc.), and catch hallucinated academic references before they reach your paper or documentation or pitch deck. Manage citation collections, import/export BibTeX, and batch-process references. 29 tools. One command to install: npx @turtletech/ookcite-mcp setup.

Overview

LLMs hallucinate citations. OokCite catches them.

Every LLM invents references. Plausible DOIs, real author names, convincing titles -- for papers that never existed. OokCite validates every citation against a real database before it reaches your paper, grant proposal, or pitch deck.

One tool call instead of twenty web searches

Without OokCite, an agent verifying citations has three options, all of which are wasteful:

Web search: each DOI fires a separate tool call, fetches a full web page, and the model parses kilobytes of HTML to extract a few metadata fields. 20 references = 20 searches, each burning tokens on irrelevant content, paywalls, and broken markup.
Raw CrossRef API: the agent constructs URLs, handles pagination, parses nested JSON, and formats output. Hundreds of tokens of reasoning per citation, spent on plumbing.
Python script (habanero, requests): spawns a code execution sandbox, installs dependencies, writes a script, runs it, parses the output. All to get a title and author list.

OokCite replaces all of that. The model sends a DOI, gets back structured metadata in milliseconds. batch_format resolves 20 messy citations in one call -- not 20 separate web searches. For agentic workflows processing dozens of references, the token savings compound quickly.

Tools

Validate before you cite

validate_doi -- confirm a DOI exists before including it
verify_references -- batch-check an entire reference list in one call
reverse_lookup -- paste a messy or partial citation, get the real paper

Format in any style

format_citation -- APA, IEEE, Chicago, Nature, and 2,900+ CSL styles
batch_format -- format multiple citations at once
search_styles -- find the right CSL style ID by name
group_cite -- generate grouped markers like [1-3, 7]

Manage collections

Save citations to named collections
Import BibTeX and RIS files
Export as BibTeX with Better BibTeX citation keys
Search, tag, reorder, and deduplicate entries
Share collections via link

29 tools total. Full list in the README.

Anti-hallucination prompt

Add this to your system prompt:

Before citing any paper, use validate_doi to confirm the reference exists. If validation fails, do not include the citation.

Install

One command:

npx @turtletech/ookcite-mcp setup

Auto-detects Claude Desktop, Claude Code, Cursor, Codex, and writes the config. Or add manually:

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

Also available via cargo binstall ookcite-mcp (no Node.js needed) or as pre-built binaries for Linux, macOS, and Windows.
