TrustBench

lithvall/trustbench

If you're building agents that make paid x402 calls, this gives you three verification primitives: query TrustBench's provider rankings across Base and Solana networks, fetch cryptographically signed payment receipts by ID, and verify Ed25519 signatures plus on-chain settlement status without trusting a third party. The registry covers roughly 650 services on Coinbase Agentic Market and 150 Solana endpoints from Heurist Mesh, with nightly liveness probes and a public scoring methodology. Every receipt links to an immutable audit trail at trustbench.io/receipts, and the verification tool checks both signature validity and Base settlement in one call. Reach for this when you need proof that an x402 payment actually settled, or when you want ranked provider discovery before routing a paid request.

Install

From registry metadata

$ npx add-mcp https://trustbench.io/mcp --name trustbench

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http trustbench https://trustbench.io/mcp

Run in your terminal. Add --scope user to make it available in every project.

Readme

TrustBench

Verify that x402 payments settled on-chain and get cryptographically signed proof. POST /verify with a receipt ID or raw envelope to confirm Ed25519 signature validity + on-chain settlement on Base, no trust required.

Also routes paid x402 calls with server-side spend caps, idempotency, and a fail-safe paywall (agent isn't charged when the upstream merchant is non-conformant). Non-custodial: TrustBench never holds funds. Every paid call emits an Ed25519-signed receipt verifiable offline against a published public key.

Cross-network: routes Base today, registers Solana endpoints (Heurist Mesh, Pay.sh skills), Solana settlement next.
