Overview

AI-generated overview

Taste connects an AI assistant to paid human experts who review content, verify claims and reasoning, approve high-stakes actions, and issue on-chain review and

What you can do
List offerings, prices and expert availability, and poll results by session or order reference code (free). Verify Taste content certificates on-chain (free). Submit content, sources, reasoning chains or plans for human review and get verdicts, often with a certificate. Ask a human a plain question, consult a named domain expert, or have a human rate content as a target audience member. Request human approval before an irreversible action, or have an arbiter settle a dispute. Order 30- or 60-minute think tank sessions and spend free revision turns on completed orders.
When to use it
Use it when an assistant's output or planned action depends on judgment a model cannot reliably supply: checking external claims, catching hallucinations or mid-chain reasoning errors, brand and cultural safety before publishing, audience reaction before ad spend, or human sign-off before an irreversible step.
Requirements
Remote streamable HTTP endpoint; nothing to install. No API key or account. Paid tools require an x402 payment in USDC on Base mainnet, signed with a wallet (EIP-3009 transfer authorization); clients without wallet integration can use a browser checkout URL. Network access to the endpoint and Base.
Before you install
Most useful tools cost money per call (about $1 to $15 in USDC on Base), and payment is signed from a wallet, so spending limits matter. Calls send your content, code, plans or claims to a third-party human review service. Some tools pause workflows for approval or settle disputes, so their verdicts affect downstream actions. Review and approval tools issue on-chain certificates that are publicly verifiable.

Installation

In SourceWeft

  1. Open Taste in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.humantaste%2Ftaste-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

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.

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

bash
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.

list_offerings

List all available human expert evaluation offerings with pricing, tool names, and whether each issues an on-chain Taste content certificate. Free.

Takes no parameters.

list_expert_profiles

Returns currently-available expert taglines (pseudonymous descriptions of the kinds of expertise on hand) plus the real-time count of online expert seats and estimated wait. Use this as a cheap pre-flight check before calling a paid tool. Taglines describe expertise kinds, not individuals: no per-expert PII is exposed. Free.

Takes no parameters.

get_result

Check the status of a previously submitted request. Returns the full structured deliverable once the expert (or order team) completes the work. Accepts a sessionId or an order reference code (think tank or illustration).

ParameterssessionIdreferenceCode

prepare_consult_domain_expert

Get a humantaste.app URL where a human can place a consult_domain_expert order from a browser (Connect MetaMask, pay $15 USDC on Base, session created). Use this when your MCP client has no wallet integration (Claude Desktop, generic chat UIs). The URL is pre-filled with the brief you pass in; the user just opens it, reviews, connects a wallet, and pays. Returns the payment URL and the price. Free.

ParametersdomainrequiredcontextquestionrequiredreferenceUrlsparentSessionId

request_think_tank_revision

Spend a free revision turn on a completed think tank order. Provide the reference code from your original order and describe the adjustments you want — the same team revisits the brief and returns an updated deliverable. Poll get_result with the reference code to retrieve it. Free: no payment required, the turn is included with your order.

ParametersadjustmentsrequiredreferenceCoderequired

verify_external_source

Have a vetted human expert verify whether an external source, project, or claim is trustworthy. Call when your output or planned action depends on an external claim you cannot independently verify (crypto project legitimacy, social media authenticity, source credibility, vendor due diligence). Returns verdict, red flags, positive signals, confidence score.

Parameterscontextsubjectrequired

review_content

Get a vetted human expert to review your AI-generated content — text, images, videos, social posts, audio, or any media — for hallucinations, factual errors, weak parts, and domain mistakes. Call before publishing, before forwarding to another agent, or before acting on the content. Returns verdict, issues found, suggested improvements. Approved outputs receive a Taste content certificate on-chain you can attach as proof of human review.

Parameterscontentrequiredcontext

verify_reasoning_chain

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, flagged errors, suggested corrections. Approved chains receive a Taste content certificate on-chain.

Parameterschainrequiredcontext

prepublish_review

Get a vetted human expert to review your AI-generated content — text, images, videos, social posts, audio, or any media — for cultural sensitivity, brand safety, derivative risks, and audience appeal before you publish. Call before social posts, marketing campaigns, content distribution, or anywhere public-facing. Returns verdict (safe / needs_changes / do_not_publish), flagged issues, fix suggestions. Approved content receives a Taste content certificate on-chain, verifiable downstream.

Parameterscontentrequiredcontext

predict_audience_reaction

Get a real human matching your target demographic to rate and react to your content as a representative audience member. Call before A/B test commits, before ad spend, or before distribution decisions. Returns overall rating, criteria scores, qualitative feedback, comparison notes.

ParameterscontentrequiredcontexttargetDemographicrequired

arbitrate_dispute

Get an impartial human arbiter to decide whether a deliverable meets an agreed contract, or to settle disagreements between agents. Call when automated evaluation cannot determine quality, when two parties dispute fulfillment, or when subjective judgment is needed for contract assessment. Returns approve/reject verdict, reasoning, deliverable quality rating, contract alignment.

ParameterscontexttermsUritermsHashtermsJsondeliverablerequiredpartyAPositionrequiredpartyBPositionrequiredcontractDescriptionrequired

request_human_approval

Pause your workflow for explicit human approval before executing a high-stakes action. Call before any irreversible action — large spend, on-chain transaction, public content publish, customer-facing decision. Returns approved/denied + reasoning. Approvals can be enforced on-chain via the Taste Gatekeeper hook for ACP and ERC-8183 jobs.

ParametersstakesrequiredcontexttimeoutMinutesactionDescriptionrequired

verify_certificate

Verify a Taste content certificate on-chain. Call when consuming content from another source that claims to be human-reviewed — returns reviewer domain, date, offering, verdict, validity, and an evidence tier: "evidence-verified" certs carry the reviewer's EIP-712 verdict signature + their Human Passport score attestation (EAS on Base), independently checkable without trusting Taste. Free. Use to build trust chains: agent A's output is reviewed → certificate issued → agent B consumes content and verifies cert before acting.

ParameterscontentHashcertificateId

order_think_tank_session_30

Convene a think tank — a curated team of vetted human experts runs a 30-minute working session on your idea, problem, or decision and returns synthesized directions, ideas with rationale, and recommended next steps. Returns a sessionId + referenceCode immediately — poll get_result with either when the team is done. Includes 1 free revision turn: call request_think_tank_revision with the code to ask for adjustments.

ParametersmediaUrlsdescriptionrequiredbuyerWalletAddressrequestedDeliverables

consult_domain_expert

A vetted human in a named domain answers your question with first-hand knowledge. Pass `domain` to match an expert. Pass `parentSessionId` for follow-ups (cap 3). Returns answer, anonymised role, confidence, first-hand flag. Approved answers get an on-chain Taste cert. Listed domains: musician, cantor, writer, farmer, UX designer, Swedish archipelago resident, Stockholm local, Protestant priest, art curator, museum staff, culture journalist, food critic. Other domains: best-effort 24-48h.

ParametersdomainrequiredcontextquestionrequiredreferenceUrlsparentSessionIdbuyerWalletAddressrequireListedDomain

ask_a_human

Ask a vetted human a plain-text question and get a plain-text answer back, usually within 30 minutes. Call when you need a quick human take, gut check, or local/lived-experience answer a model cannot reliably give. No scoring, no verdict, no certificate — just a direct human response. Returns the human's answer, plus an optional note on who answered.

Parametersquestionrequired

review_plan

Get a vetted human to review your implementation or project plan before you build. Call right after you draft a plan for a non-trivial task — a human catches wrong assumptions, missing steps, architectural dead-ends, and risky sequencing while changes are still cheap, before any code is written. Pass the plan, the goal it serves, and any constraints. Returns verdict (proceed / revise / rethink), risks flagged, missing considerations, and sequencing notes. Approved plans receive a Taste content certificate on-chain.

Parametersgoalrequiredplanrequiredcontext

review_code

Get a vetted human engineer to review your code, architecture, and design decisions — not just style, but correctness, security, and whether the structure will hold up. Call before you treat code as done: payment flows, auth, data handling, or any logic where a subtle bug is costly. Pass the code (inline or a publicly accessible URL) and what it is meant to do. Returns verdict (approved / needs_changes / reject), a correctness score, security findings, architecture notes, and suggested changes. Approved code receives a Taste content certificate on-chain.
