MCP SERVER · OPEN · NO AUTH

Verify AI receipts from inside any AI tool.

Install Sovereign as an MCP server. Verify any agent-run receipt, fetch the freshest public one, or stream the live feed — directly from Claude Desktop, Claude Code, Cursor, or any MCP-compatible client. One config line. No API key.

Tools exposed

verify_receipt

Verify any Sovereign receipt by passing canonical + signature. Returns {valid: true|false} — same endpoint compliance auditors use.

fetch_receipt

Pull a receipt by id. Returns canonical + signature + agent name + model + timestamps. Visibility-gated: only public/unlisted receipts.

latest_public_receipt

Get the freshest public receipt. Useful for 'show me what was just signed' demos in AI tools.

recent_public_receipts

Feed of the last N public receipts (1-50, default 10). Each row is a fingerprint summary — call fetch_receipt for full data.

Hit the endpoint directly

The server speaks JSON-RPC 2.0 over HTTP — installable clients are the easy path, but curl works too:

curl -X POST https://sovereignmatrix.agency/api/mcp/verifier \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'

Or visit /api/mcp/verifier in a browser for the GET self-description.
