An MCP server that mirrors the skills and workflows of an industry-leading research institute — academic rigour and private-sector pragmatism — exposed to any MCP-capable client (Claude Desktop, Claude Code, Antigravity, and others).

research_mcp encodes the craft of research as a set of reasoning tools, a curated knowledge base, and end-to-end workflows. It is grounded in a defensible canon of methodological authority (see SOURCE_AUTHORITY.md) so that its guidance is principled and consistent, not improvised.

It runs locally over stdio, so it composes with tools already on your machine — curl/wget for retrieval and your installed Chrome (via Playwright) for JavaScript-heavy pages — and with free, keyless scholarly APIs (OpenAlex, Crossref, arXiv, OSF) plus Unpaywall for open-access full text. HTML and PDF are converted to text in-process (no pandoc/pdftotext required).

The research lifecycle

A great research institute does a handful of things exceptionally well, in sequence. research_mcp provides a tool, a workflow, or both for each stage:

   scope ──▶ design ──▶ instrument ──▶ find & appraise ──▶ synthesise
                                                               │
   translate ◀── govern ◀── review ◀── analyse ◀──────────────┘

The methodology core is domain-agnostic — it works for any field — with an optional HR / people-analytics lens that adds presets, workforce-survey templates, and a "translate findings into an HRLT or board brief" capability.

Architecture

research_mcp (stdio MCP server, TypeScript)
├── tools/        reasoning skills (scope, design, appraise, synthesise, review, translate…)
├── resources/    the knowledge base (methodology canon, reporting standards, ethics)
├── prompts/      end-to-end workflows (systematic review, study-design sprint, evidence brief…)
└── lib/          codified canon, scholarly connectors, the retrieval ladder, in-process extraction

Local-first by design. Running on your machine, retrieval carries your IP/VPN and a real browser User-Agent, so it reaches what you can reach; Zotero, your Obsidian vault, and system Chrome are all on localhost.
Retrieval ladder. An allow-listed curl → wget → headless-Chrome (Playwright) escalation; HTML/PDF are converted to text in-process (jsdom + Readability + Turndown; pdfjs).
Knowledge-grounded. Tools compose a codified canon (lib/data/) into structured guidance rather than improvising; conflicts resolve via SOURCE_AUTHORITY.md.

Source-quality cadence

Discovery spans peer-reviewed literature and the open web, governed by a 7-tier source-quality cadence: syntheses → peer-reviewed → preprints → official/primary documents → expert secondary → interested primary → general web. Results are ranked so cited, peer-reviewed work outranks zero-citation preprints, but the cadence descends legitimately for novel or fast-moving topics (e.g. an emerging AI legal matter) where primary documents and expert analysis outweigh thin academic evidence. appraise-source weighs any non-study source by provenance and interest.

Quick start

git clone https://github.com/simonives/research_mcp.git
cd research_mcp
npm install
npm run build
npm start          # runs the server over stdio

claude mcp add research -s user -- node "$(pwd)/dist/index.js"

Or add to a Claude Desktop / Antigravity MCP config block pointing at dist/index.js. Reconnect/restart the client after registering or rebuilding so it picks up the latest tools.

Configuration

Configuration is supplied via environment variables, or a gitignored .env in the project root — copy .env.example and fill it in. The server loads .env on startup (resolved relative to the project, so it works from any directory); anything already set in the environment or MCP-client config takes precedence. All variables are optional — the offline core needs none.

Variable	Enables
`RESEARCH_MCP_OBSIDIAN_VAULT`	Path to an Obsidian vault → activates the `vault-*` tools
`RESEARCH_MCP_ZOTERO_URL`	Override the Zotero local API base (default `http://localhost:23119/api`)
`RESEARCH_MCP_CONTACT`	Email for scholarly-API "polite pools" and to enable the Unpaywall OA resolver
`RESEARCH_MCP_USER_AGENT`	Override the browser User-Agent used by `fetch-url`
`RESEARCH_MCP_CACHE_DIR`	Where retrieved files and API responses are cached
`RESEARCH_MCP_BRAVE_KEY`	Brave Search API key → reliable backend for `web-search` (free tier)
`RESEARCH_MCP_SEARXNG_URL`	A SearXNG instance URL → self-hosted backend for `web-search`
`RESEARCH_MCP_SEARCH_BACKEND`	Force `web-search` backend: `duckduckgo` (default, keyless best-effort), `brave`, or `searxng`

Note on web-search: keyless scraping (DuckDuckGo) is frequently bot-blocked from a server IP. For reliable server-side web search, set RESEARCH_MCP_BRAVE_KEY or RESEARCH_MCP_SEARXNG_URL; otherwise use the assistant's own web search for discovery and fetch-url to retrieve. Shadow libraries (e.g. LibGen) are deliberately not integrated; for paywalled works use Unpaywall OA, a cookie_file for entitled access, or interlibrary loan.

Zotero tools also require the Zotero 7+ desktop app running with its local API enabled.

Development

npm run build        # compile TypeScript → dist/
npm run dev          # run from source with tsx
npm run typecheck    # type-check without emitting
npm test             # regression harness over stdio (offline, CI-safe)
npm run test:online  # + live connector checks (network)

The test harness (scripts/smoke-test.mjs) drives the built server over the MCP protocol and asserts the contract of every tool, prompt, and resource — run it after any change. Contribution guidelines are in CONTRIBUTING.md.

Knowledge integrity

This server makes claims about research methodology. When sources conflict, it resolves them using an explicit authority hierarchy documented in SOURCE_AUTHORITY.md. Contributions that enrich the knowledge base must follow that hierarchy.

Built with Claude Code

research_mcp was designed and built with Claude Code (Anthropic) — from the initial scaffolding through implementation, live testing, and configuration — pair-built with its author. The methodology it encodes remains grounded in the human authorities catalogued in SOURCE_AUTHORITY.md.
