A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
pipeline
pipeline_invoke
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.
pipeline_prepare
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
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
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.
pipeline_refund_status
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
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.
market
market_invoke
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).
market_search
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.
air
air_quality_now
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 3 priced calls per caller are free.
nearby
nearby_sensors
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 3 priced calls per caller are free.
weather
weather_now
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 3 priced calls per caller are free.
x402
x402_check
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 3 priced calls per caller are free.

Attested Memory Market — questions
Answers built from our own checks of this server.
What can Attested Memory Market do?
It exposes 12 tools, read directly from the server on our last check. Among them: air_quality_now, market_invoke, market_search, nearby_sensors, pipeline_invoke, pipeline_prepare and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is Attested Memory Market mostly used for?
Its tools cluster around pipeline and market. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Attested Memory Market working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 349 ms. The bar chart above shows every period we have measured.
Did Attested Memory Market ever remove tools?
Yes. fair_random is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Attested Memory Market?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Attested Memory Market need an API key?
No. Attested Memory Market completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Attested Memory Market?
It answers our handshake in 349 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Attested Memory Market open source?
The code is open source: it is published under the Apache-2.0 licence, written in Python and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at hub.attestedmemory.net, which runs on its operator's own terms.
