Real-time fact-check, citation verification, and source-freshness for AI agents.
Real-time fact-check, citation verification, and source-freshness for AI agents. Exposed over MCP by the citation verification mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
Hosted MCP server that fact-checks an LLM's claims and citations in real time. Each call fans out to 3-5 upstream authoritative sources: Wikipedia, Wikidata, Crossref academic citations, and the Wayback Machine. Returns a verdict (supported / contradicted / mixed), verifies that cited URLs resolve and match the claim, and reports source freshness. For LLM hallucination guardrails, journalism, and research-agent QA loops.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Everything the assistant can do here goes through one of these:
fact_check — claim, max_sources?cite_check — urls[], claim?source_freshness — urlPlenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Citation Verification's toolset — fact_check, cite_check, source_freshness — is a fair guide to whether it matches your workflow. It is maintained by guptaprakhariitr; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
| Tool | What it does |
|---|---|
| fact_check | claim, max_sources? |
| cite_check | urls[], claim? |
| source_freshness | url |
Or wire it into your MCP client:
```jsonc
{
"mcpServers": {
"verification": {
"command": "npx",
"args": ["-y", "@insnapsprakhar/verification-mcp"]
}
}
}Configuration as documented by the project. Restart the client after saving.
