kodiak-mcp

Verifiable fact-checking for agents. An MCP server that lets an agent check a factual claim before relying on it — and get back a verdict, a calibrated confidence, cited sources, and a tamper-evident certificate anyone can verify. Built so a pipeline can't silently ship confabulated facts.

Install

No npm registry needed — it runs straight from GitHub. Add to your MCP client config (Claude Code, Copilot, etc.):

{
  "mcpServers": {
    "kodiak": {
      "command": "npx",
      "args": ["-y", "github:bildow/kodiak-mcp"],
      "env": { "KODIAK_API_KEY": "your-key" }
    }
  }
}

Tools

• kodiak_check_claim — verify one factual claim. Args: claim (required), depth (1–5, default 3). Returns verdict (supported / false / mixed / unsupported), confidence (0–100), citations, sub-claim breakdown, certificate_id, and a verify_url. A few cents of credit per call.
• kodiak_verify_certificate — recompute a certificate's hash chain to confirm it's exactly as certified. Args: certificate_id. No key or credits required.
• kodiak_credits — check your balance and current pricing.

Why it's different

Every certificate is hash-chained and externally anchored (Buoy + OpenTimestamps/Bitcoin), so a verdict's provenance is provable after the fact, not merely asserted. Verify any certificate at https://azurecarbon.com/verify/{certificate_id} — including ones you didn't produce.
