Which integrations are available for this server?

Resolves DOIs via doi.org to verify paper metadata, retraction status, and journal integrity as part of IntegrityLens. Integrates with Google Fact Check Tools API to check if a claim or page has been fact-checked, returning ClaimReview data for ClaimTrail. Integrates with Meta Ad Library to search for ads run on Meta platforms (Facebook, Instagram, etc.) as part of DSA-Lens transparency research. Integrates with the npm registry to verify package existence, safety, and metadata for dependency verification in DepCheck. Integrates with the PyPI registry to verify package existence, safety, and metadata for dependency verification in DepCheck. Integrates with Trend Micro's slopsquatting dataset to detect potentially malicious or hallucinated package names in DepCheck.

How do I use SiteGraph?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@SiteGraph who operates nytimes.com and what other sites share its operator?" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

agent-osint

Seven organisation-focused OSINT servers for AI agents, speaking the Model Context Protocol. Attach them to Claude, Cursor, or any MCP client and your agent gains verifiable, evidence-backed answers to questions LLMs cannot answer from memory.

Server	Question it answers	Key sources	Needs a key?
SiteGraph	Who operates this website, and which other sites share its operator?	ads.txt / app-ads.txt, sellers.json, analytics & tag IDs, legal notices (Impressum), security.txt, Certificate Transparency, Wayback, Common Crawl	No (optional `CERTSPOTTER_API_KEY`)
CommentForensics	Which public comments on a US rulemaking are coordinated form-letter campaigns, and who is behind them?	Regulations.gov API v4, Mirrulations mirror, bulk CSV exports	Optional (`REGULATIONS_GOV_API_KEY`; mirror needs none)
IntegrityLens	Is this paper/reference list/journal trustworthy?	Crossref (incl. Retraction Watch data), OpenAlex, doi.org, PubPeer, Problematic Paper Screener & hijacked-journal lists (you load them), tortured-phrase detector	Optional (`PUBPEER_DEVKEY`)
DSA-Lens	How do platforms moderate content in the EU? What ads ran?	EU DSA Transparency Database (Research API + daily dumps), Meta Ad Library	`DSA_TDB_TOKEN` for API route; `META_AD_LIBRARY_TOKEN` for ads. Dumps need none
Procurement Red Flags	Which public contracts show integrity risk indicators?	OCDS data (UK Find a Tender or any publisher), GLEIF, Companies House, OpenSanctions	Optional (`COMPANIES_HOUSE_API_KEY`, `OPENSANCTIONS_API_KEY`)
DepCheck	Is the package my coding agent wants to install real and safe?	PyPI, npm, popularity lists, Trend Micro slopsquatting dataset	No
ClaimTrail	When and where did this claim/page/image first appear? Has it been fact-checked?	Wayback Machine, page metadata, ClaimReview, Google Fact Check Tools, C2PA	Optional (`GOOGLE_FACTCHECK_API_KEY`)

48 tools in total — see docs/TOOLS.md. Verification status is documented honestly in VERIFICATION.md.

Design principles

Evidence on every claim. Each finding carries evidence IDs (URL, fetch time, HTTP status, SHA-256 of the raw bytes, and the bytes where lawful to keep). Read them via the <server>://evidence/{id} MCP resource.
Uniform envelope. Every tool returns {"ok", "data", "evidence", "warnings", "limitations", "sources_checked"} or {"ok": false, "error": {"code", "message", "hint"}} — agents never see stack traces.
Organisations, not people. Names that look like private individuals (sole traders, commenters, signatories, PubPeer users, ad payers) are withheld; personal emails and phone numbers are masked. There is no switch to disable this.
Polite by default. Conservative per-host token-bucket rate limits (matching providers' published limits where they publish them), retries with Retry-After, robots.txt (RFC 9309) for HTML pages, response-size caps, and a local response cache.
Safe to expose to an agent. Requests to loopback/private/link-local addresses are refused (SSRF guard), local file inputs can be confined with AGENT_OSINT_FILE_ROOTS, and file types are checked.
Honest outputs. Scores are tiers with stated rules, "no signal" is never presented as "clean", and every tool lists its limitations.

Install

Requires Python 3.10+.

pip install ./agent-osint            # from this folder
pip install "./agent-osint[c2pa]"    # + C2PA reading for ClaimTrail

Or run without installing, with uv: uvx --from ./agent-osint agent-osint-depcheck.

Docker: docker build -t agent-osint . then docker run -i --rm agent-osint agent-osint-depcheck.

  }
}

Claude Code — claude mcp add depcheck -- agent-osint-depcheck (repeat per server; add -e KEY=value for env).

Cursor / other clients — any MCP client that launches stdio servers works with the same commands. For remote use, run agent-osint-<server> serve --transport streamable-http.

Responsible use

These tools surface public information about organisations. Shared identifiers, form-letter campaigns and procurement red flags are indicators for further review, not proof of ownership, fraud or corruption. Verify before you publish, give organisations a chance to respond, and respect each data source's terms of use (see NOTICE and VERIFICATION.md).
