Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.

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. Attest your agent's verification results with MINT Protocol. 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 |
|---|---|---|
verify_claim | $0.02 | Verify a claim → verdict, confidence, cited sources, explanation |
batch_verify | $0.01/claim (min $0.05) | Verify many claims in one call |
source_check | $0.01 | Assess a source URL — domain age (RDAP), trust signals, bias indicators |
daily_brief | $5 | Curated daily brief — top disputed/most-verified claims, trending topics |
mint_info | free | FoundryNet Data Network + MINT Protocol |
Free tier: 10 verifications/day per agent. Then x402: the tool returns an
HTTP-402 with a Solana USDC payment memo — 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:
brand-intel-mcpfinancial-signals-mcppatent-intel-mcpcompliance-mcpThe 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 MINT 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.
