Install

How do I install the TrustBench MCP server?

TrustBench is a hosted endpoint at https://trustbench.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 3 exposed · ~637 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_rankings ~151

Get TrustBench liveness rankings for x402 providers by capability. Returns a scored list of providers with latency and success-rate telemetry. Methodology note: scores are derived from HEAD-probe liveness checks (3 samples from one host), not a rigorous benchmark. See trustbench.io/methodology. Output: returns a JSON array. Each object has name (string, provider name), score (number 0-100, composite liveness score), latency_p50 (number, ms), success_rate (number 0.0-1.0, last 7 days), endpoint (string, URL), capabilities (array of strings).

No examples provided.

get_receipt ~221

Fetch a TrustBench routing receipt by ID. Receipts are immutable, Ed25519-signed records of a routing or payment event. Use to verify what was paid, to whom, for what capability, and what the on-chain settlement reference is. IDs start with rcpt_ (Phase 3) or rrcpt_ (Phase 4). Output: returns the signed receipt envelope as JSON. Phase 3 (rcpt_) returns a SignedReceipt with receipt (call metadata + settlement ref) and signature (Ed25519 over JCS-canonicalized receipt body). Phase 4 (rrcpt_) returns {receipt, signature} where receipt.paid contains routing details and signature covers the canonical envelope. To verify an envelope offline use the verify_receipt tool with the returned JSON, or @trustbench/verify-receipt npm.

verify_receipt ~265

Verify the Ed25519 signature on a TrustBench receipt. Two modes: (1) Lookup mode — pass receipt_id and the server fetches the receipt from trustbench.io and re-runs verification (handy when you only have an ID). (2) Offline mode — pass receipt_json (the full {receipt, signature} envelope an agent received from a third party) and the server verifies the Ed25519 signature against the published public key at trustbench.io/.well-known/trustbench-pubkey without trusting the database. Exactly one of receipt_id or receipt_json must be provided. Output: returns JSON with receipt_id, signature_valid (boolean), on_chain_verified (boolean, where present), signature_alg ("ed25519"), verify_url, pubkey_url. For non-server-mediated verification with no network round-trip, use the @trustbench/verify-receipt npm package.

Common questions

What is the TrustBench MCP server?

TrustBench is an MCP server listed in the public MCP registry as io.github.lithvall/trustbench. x402 provider rankings + Ed25519-signed payment receipts + signature verification (3 tools). This page covers its hosted endpoint (https://trustbench.io/mcp).

Is the TrustBench MCP server safe to use?

TrustBench scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the TrustBench MCP server expose?

TrustBench exposes 3 tools: get_rankings, get_receipt, verify_receipt. Their descriptions and schemas cost roughly 637 tokens of context every time the server is loaded.

Does the TrustBench MCP server require authentication?

No. We connected to TrustBench without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the TrustBench MCP server still maintained?

TrustBench is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
