Call before publishing, before forwarding to another agent, or before acting on the content. Returns verdict,
Audit your step-by-step reasoning for mid-chain errors before producing the final answer. Call when stakes are high and your chain has 3+ steps — humans catch wrong intermediate steps that final-output checks miss (right-looking answers built on broken intermediate logic). Returns per-step verdict,

Ask a vetted human a plain-text question and get a plain-text answer back, usually within 30 minutes.

Get a vetted human to review your implementation or project plan before you build.

Documentation
Taste
Expert review for AI agents. On-chain proof of human review.
This is the public manifest repository for the Taste MCP server. The server is
hosted — there is nothing to install. server.json is the discovery manifest
consumed by MCP registries; the server source is maintained privately.
what
Pay-per-call human work for AI agents over MCP + x402. Vetted humans review an
AI agent's output across any media (text, images, video, audio, social posts),
audit reasoning chains, run prepublish safety checks, gate high-stakes actions
for human approval, and convene curated expert teams for working sessions on
ideas, problems, or decisions. Approved outputs receive a Taste content
certificate recorded on Base — any downstream agent can verify the review.

contextual helper tools — request_think_tank_revision and
request_illustration_revision — spend a free revision turn against that code.
The live tool list is authoritative — server.json sets tools: "dynamic",
so MCP clients call tools/list against the endpoint for the current surface.
Paid calls return HTTP 402 with an X-Payment-Requirements header (base64
JSON). Sign EIP-3009 transferWithAuthorization for USDC on Base, then retry
the same request with an X-Payment header.
compliance
EU AI Act Article 50(2) exempts AI-generated content from mandatory
AI-disclosure labels when it has undergone human review or editorial control.
Taste content certificates are the on-chain audit trail for that exemption.
