Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Fact Check MCP is it true that the Earth is flat?"
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.
Fact verification for AI agents — give it a claim, get a verdict
(supported / disputed / unverifiable) with a 0-100 confidence and cited
sources. It classifies each claim's domain and cross-references the FoundryNet
Data Network plus a general web search.
Part of the FoundryNet Data Network. Verification results carry a verifiable provenance attestation. See also: financial-signals-mcp, cyber-intel-mcp, patent-intel-mcp, gov-contracts-mcp, compliance-mcp, brand-intel-mcp, weather-intel-mcp, academic-intel-mcp, oss-intel-mcp, social-intel-mcp.

Tool | Price | What it does |
| $0.02 | Verify a claim → verdict, confidence, cited sources, explanation |
| $0.01/claim (min $0.05) | Verify many claims in one call |
| $0.01 | Assess a source URL — domain age (RDAP), trust signals, bias indicators |
| $5 | Curated daily brief — top disputed/most-verified claims, trending topics |

Free tier: 10 verifications/day per agent. Then metered: the tool returns an
HTTP-402 payment challenge — pay it, re-call with the same args plus
payment_tx=<signature>. An Authorization: Bearer fnet_… key bypasses the paywall.
Each claim is classified by domain and cross-referenced against the most relevant FoundryNet data source and a general web search:
company claims → brand-intel-mcp
finance claims → financial-signals-mcp
patents claims → patent-intel-mcp
regulation claims → compliance-mcp
The verdict is synthesized from source agreement and returned with the citations that drove it. Results are cached for 24h (keyed by a normalized-claim hash) and carry a verifiable provenance attestation so a buyer can verify the result was produced by this server, unaltered.
The general web-search backend needs a
WEB_SEARCH_API_KEY(Brave Search API). Without it, claims with no FoundryNet corroboration returnunverifiablewith a note rather than a guess.
On demand: a general web search (Brave Search API) + the FoundryNet Data Network sibling servers (called over their public MCP endpoints). Source-credibility checks use keyless RDAP for domain age. Cached in a standalone Supabase project.
