- Non-custodial — TrustBench never holds agent funds.
- Three read-only tools: rankings, receipts, verification.
- Ed25519 signature verification (lookup by ID or offline).
- No API key required for MCP tools.
- Supports both stdio and Streamable HTTP transports.
Install via npx -y @trustbench/mcp for stdio-based MCP hosts (Claude Desktop, Cursor, Cherry Studio, Kimi) or use the hosted Streamable HTTP endpoint at https://trustbench.io/mcp for browser-based MCP clients. No API key is required for any of the MCP tools.
Native MCP server forTrustBench— a non-custodial routing and audit layer for x402 agent payments.
Adds three read-only tools to any MCP-capable host:
Works inClaude Desktop, Claude Cowork, Grok(xAI Connectors),Kimi Code CLI,Cherry Studio,Cursor, and any MCP-compatible host.
Add to your host's MCP config file (e.g.claude_desktop_config.jsonfor Claude Desktop,~/.kimi/mcp.jsonfor Kimi):
{ "mcpServers": { "trustbench": { "command": "npx", "args": ["-y", "@trustbench/mcp"] } } }
Restart the host app. The three tools above become available immediately — no API key, no account required.
get_rankings— JSON array of scored providers for the requested capability. Capabilities:search,inference,data,media,infra. Scores are derived from HEAD-probe liveness checks (3 samples from one host). Seetrustbench.io/methodologyfor the full scoring formula.
get_receipt— Full signed receipt envelope. Receipts are immutable after issuance. Phase 3 IDs start withrcpt_, Phase 4 routing receipts start withrrcpt_.
verify_receipt— Two modes (provide exactly one input):
- Lookup mode(receipt_id) — fetches the receipt fromtrustbench.ioand re-runs Ed25519 + on-chain verification. Useful when the agent only has an ID.
- Offline mode(receipt_json) — verifies a full{receipt, signature}envelope an agent received from a third party against the published public key, without trusting the database. The third-party-verifier path.
Both modes return a JSON summary withsignature_valid(boolean),on_chain_verified(boolean where applicable),signature_alg(ed25519), andpubkey_url. For zero-network verification with no round-trip to TrustBench, use the@trustbench/verify-receiptnpm package instead.
route_quoteandroute_settle(the paid routing flow) require atb_live_…API key and ship in the next release. Request access by DM'ing@TrustBench on X.
- Transport: stdio (JSON-RPC 2.0) — the MCP standard
- No external dependencies beyond Node.js built-ins
- Node ≥ 18 required (uses nativefetchandreadline)

- @trustbench/verify-receipt— standalone offline Ed25519 receipt verifier
