What is the VouchSpec Agent Skill Evidence MCP server?

Read-only discovery for exact-commit Agent Skill validation, x402 payment, and signed receipts. That is what the vouchspec agent skill evidence mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

VouchSpec is the provisional public-beta name for an independent evidence index for exact Agent Skill versions. The name passed a $0 obvious-conflict screen; it has not received formal legal or trademark clearance.

Getting it running

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

What it needs from you

Configuration is passed through the environment: RECEIPT_ID. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

How it compares

Among the payments and commerce options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by mordiaky; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against VouchSpec Agent Skill Evidence's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Things to watch

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
