markovian-mcp

Bitcoin-anchored, independently verifiable provenance for AI outputs, exposed as MCP tools.

Trust the emitter? No. Prove the emitter. Commit an output to a canonical root, verify it later by pure recomputation, and trace its lineage. No operator to trust; verification is offline.

Tools

• markovian_stamp(content) — compute the canonical commitment root for an output. JSON is canonicalized with RFC 8785 (JCS), other text verbatim, then SHA-256 hashed. This root is what Markovian anchors to Bitcoin.
• markovian_verify(content, canonical_root) — recompute the root and check it. One changed byte fails the check.
• markovian_trace(receipts_json) — walk a lineage of stamps back to its origin.

Install

pip install markovian-mcp

Configure (Claude Desktop / Cursor / Claude Code)

{
  "mcpServers": {
    "markovian": {
      "command": "markovian-mcp"
    }
  }
}

Verify offline

markovian_stamp and markovian_verify are pure functions. Anyone can recompute a root over the same bytes and get the same answer, with nothing trusted from us. Learn more at markovianprotocol.com.
