About Taste
Taste is a hosted MCP server that routes AI work to vetted human experts for review, approval, and collaborative sessions. Its paid calls use x402 with USDC on Base, and reviewed outputs can receive certificates recorded on-chain.

MCP support
Provides free discovery, result, and certificate tools, plus paid human-review tools to MCP clients. Paid calls use x402 payments in USDC on Base.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project READMETaste
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.
connect
MCP endpoint: https://api.humantaste.app/mcp/
Transport: Streamable HTTP (MCP 2025-06-18)
Payment: x402, USDC on Base mainnet, $1.00–$15.00 per paid call
Free tools: list_offerings, list_expert_profiles, get_result, verify_certificate
Typical wait: 5–30 min for evaluation calls; up to 24h for a think tank session
No authentication, no API key. Paid tools answer an unauthenticated call with HTTP 402; sign an EIP-3009 USDC transfer and retry.
tools
Free (no payment, no session):
| Tool | Purpose |
|---|---|
list_offerings | list offerings, prices, certificate flag, operating-hours state |
list_expert_profiles | aggregate availability + estimated response time, no PII |
get_result | poll session status by sessionId or order reference code; returns the full deliverable when complete |
verify_certificate | read-only Taste content certificate lookup on Base, rate-limited 60/min/IP |
Paid (x402 — USDC on Base):
| Tool | Price | Purpose |
|---|---|---|
verify_external_source | $1.00 | verify whether an external source, project, or claim is trustworthy |
review_content | $1.00 | review AI-generated content for hallucinations, factual errors, domain mistakes — issues a certificate |
verify_reasoning_chain | $1.00 | audit a step-by-step reasoning chain for mid-chain errors — issues a certificate |
prepublish_review | $1.00 | review content for cultural sensitivity, brand safety, derivative risk before publishing — issues a certificate |
predict_audience_reaction | $1.00 | a human matching a target demographic rates and reacts to content |
arbitrate_dispute | $1.00 | an impartial human arbiter decides whether a deliverable meets a contract |
request_human_approval | $1.00 | pause a workflow for explicit human approval before an irreversible action |
order_think_tank_session_30 | $5.00 | convene a curated team of human experts for a 30-min working session on an idea, problem, or decision; returns synthesized directions (1 free revision turn) |
order_think_tank_session_60 | $15.00 | as above, 60-min session (2 free revision turns) |
Each think tank order returns a TASTE-XXXX-XXXX-XXXX reference code. Two
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.
example
curl -X POST https://api.humantaste.app/mcp/ \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
"params":{"name":"list_offerings","arguments":{}}}'
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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
