Claude Code: ask. ### `pipeline_refund` - The name "pipeline_refund" says "refund": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Submit the original seller's refund authorization or resume the SAME refund. The recipient is the original buyer, amount is the paid step price, and the sponsor pays gas. Preserve the exact authorization after a lost response. Returns a separately signed credit note; the original bill is unchanged. ``` ### `pipeline_refund_prepare` - The name "pipeline_refund_prepare" says "refund": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Prepare a cash refund for a verified paid step of a finished pipeline. This moves no money. The original seller must approve the exact EIP-3009 authorization locally; never send a private key. Refunds require seller cooperation and a configured gas sponsor. ``` ## Changes things (7) Creates or changes something that can be changed back. Claude Code: ask. ### `air_quality_now` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Current air quality at a place: PM2.5 and PM10 (µg/m³), US and European AQI, from Copernicus CAMS via Open-Meteo, with a signed receipt. Pass latitude and longitude, or a city. Costs $0.001 per call. The first 5 priced calls per caller are free. ``` ### `fair_random` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Verifiable random bytes for a draw, raffle or tie-break: an ECVRF output over your seed plus a proof anyone can check offline. The same seed always gives the same output, so publish the seed first to show the result was not picked. Costs $0.006 per call. The first 5 priced calls per caller are free. ``` ### `market_invoke` - The name "market_invoke" says "invoke": a word for a change. Description, as the server wrote it: ```untrusted-server-text Invoke a capability found via market_search. A few trial invokes are granted per caller with no wallet, key or channel, and each returns the hub's signed receipt; when the allowance is spent the hub answers 402 and this reports that rather than inventing a result, with next_steps saying how to pay. Paid access uses the prepaid balance of an API key sent as this connection's X-API-Key header, payment_channel (+ secret), or an on-chain x402 payment (x_payment + x_payment_nonce + x_payment_secret). ``` ### `nearby_sensors` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text The nearest live public sensors to a point, one per layer asked for (e.g. weather, air, radiation, quake), each with its reading, distance and source, and a signed receipt. Costs $0.03 per call. The first 5 priced calls per caller are free. ``` ### `pipeline_invoke` - The name "pipeline_invoke" says "invoke": a word for a change. Description, as the server wrote it: ```untrusted-server-text Execute or continue the SAME prepared graph. Submit authorizations when the signed quote enables gas_sponsorship, otherwise buyer-signed transactions; none for free steps. Never submit both payment modes. Retain run_id/access_token and the exact bundle. Pending is not failure; repeat the same run or read pipeline_status. Never create a replacement purchase after a lost response. ``` ### `weather_now` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Current weather at a place: temperature (°C), humidity (%), pressure (hPa) and wind (m/s) from the nearest live Open-Meteo relay within 75 km, with a signed receipt. Pass latitude and longitude, or a city. Costs $0.001 per call. The first 5 priced calls per caller are free. ``` ### `x402_check` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Check a signed x402 USDC payment before submitting it: recovers the EIP-712 signer, runs USDC's own checks and the seller's (payTo, amount, asset, network), and when the signature fails names the domain it was really made for (e.g. Base Sepolia's 'USDC' used on Base, where USDC is 'USD Coin'). Costs $0.003 per call. The first 5 priced calls per caller are free. ``` ## Only reads (4) Looks things up and changes nothing. Claude Code: allow. ### `market_search` - The name "market_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search this hub's catalogue of live data and computation by what you need, in plain words. Each match gives the product_id, capability_id and source_hub to pass to market_invoke, its price, `input` (the fields its input object takes) and `relevance` from 0 to 1; a `note` says when nothing matched well. ``` ### `pipeline_prepare` - The description's first verb is "validate": a word for reading. Description, as the server wrote it: ```untrusted-server-text Validate a graph and return a signed quote and payment offers. No work or payment. Free steps require no wallet; paid steps require buyer wallet address. Use gas_mode=required to demand gas sponsorship or auto to prefer it. Inspect ready/blockers and gas_sponsorship. Sign offers LOCALLY, never provide a private key. Then call pipeline_invoke. ``` ### `pipeline_refund_status` - The name "pipeline_refund_status" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text Read the saved cash-refund status and signed credit note without broadcasting a transaction. No private key or RPC is required. Pending means resume the same refund, never send a replacement transfer. ``` ### `pipeline_status` - The name "pipeline_status" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text Read an existing pipeline, including cached signed result, without broadcasting payments or invoking providers. No wallet signer or blockchain RPC required. Inspect recovery.action for unresolved work. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `aimarket-hub`: ```json { "permissions": { "allow": [ "mcp__aimarket-hub__market_search", "mcp__aimarket-hub__pipeline_prepare", "mcp__aimarket-hub__pipeline_status", "mcp__aimarket-hub__pipeline_refund_status" ], "ask": [ "mcp__aimarket-hub__market_invoke", "mcp__aimarket-hub__pipeline_invoke", "mcp__aimarket-hub__pipeline_refund_prepare", "mcp__aimarket-hub__pipeline_refund", "mcp__aimarket-hub__weather_now", "mcp__aimarket-hub__air_quality_now", "mcp__aimarket-hub__nearby_sensors", "mcp__aimarket-hub__fair_random", "mcp__aimarket-hub__x402_check" ], "deny": [] } } ```
