Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

search_providersWhich payment or stablecoin providers support this asset, chain, country or service?No findings
Why it is in this group
- The name "search_providers" says "search": a word for reading.
- The description's first verb is "payment": a word that usually means money moves, which cannot be taken back.
Description, as the server wrote it
Which payment or stablecoin providers support this asset, chain, country or service? Free: search payment and stablecoin providers by category, asset, chain, ramp country or service. Returns compact cards (no citations); use get_provider for the full cited record. 50 calls/day per client.

Changes things 2Creates or changes something that can be changed back.Claude Code: ask

check_address_formatIs this address well formed for this chain, and what is its EIP-55 checksummed form?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Is this address well formed for this chain, and what is its EIP-55 checksummed form? Free: deterministic address format check for EVM chains (EIP-55 checksum: valid, checksummed form, whether the input checksum was correct, all lowercase or all uppercase) and Solana (base58, 32 bytes). No external calls. 60 calls/min per client. Format only; says nothing about who controls an address.
stablecoin_railsWho can on-ramp, off-ramp, issue or settle this stablecoin, on which chain, in which country?No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Who can on-ramp, off-ramp, issue or settle this stablecoin, on which chain, in which country? Paid ($0.01 USDC): Stablecoin rails by asset, chain, country and service, with the cited stablecoin block for each matching provider (assets, chains, ramp countries, fiat rails, custody model). Country matches say whether the country is listed or only covered by a 'global' claim. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/stablecoin-rails. Pay with your own x402/MPP client and retry that URL.

Only reads 5Looks things up and changes nothing.Claude Code: allow

find_corridorWho can move money from this currency or stablecoin to that one, in this country, over which rails?No findings
Why it is in this group
- The name "find_corridor" says "find": a word for reading.
Description, as the server wrote it
Who can move money from this currency or stablecoin to that one, in this country, over which rails? Paid ($0.03 USDC): Money-movement routes from one currency or stablecoin to another: corridors providers publish (rails, speed, fee notes, cited), plus on/off-ramp routes inferred from ramp coverage, labelled as inferred. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/corridor. Pay with your own x402/MPP client and retry that URL.
get_chainWhat are the basic facts of this chain (CAIP-2 id, gas token, explorer, x402/MPP settlement, stablecoins)?No findings
Why it is in this group
- The name "get_chain" says "get": a word for reading.
Description, as the server wrote it
What are the basic facts of this chain (CAIP-2 id, gas token, explorer, x402/MPP settlement, stablecoins)? Paid ($0.001 USDC): Cited chain facts from a prepared dataset: CAIP-2 chain id, gas token, finality class, block explorer, whether x402 and MPP settle there, and stablecoins. Fields not established from a source are the string "unknown". Unknown chains and malformed input return 404/400 and are never charged. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/chain. Pay with your own x402/MPP client and retry that URL.
get_examplesWhat do the paid endpoints return, and what do they cost?No findings
Why it is in this group
- The name "get_examples" says "get": a word for reading.
Description, as the server wrote it
What do the paid endpoints return, and what do they cost? Free: prices and paths of every paid endpoint, plus a full example response for GET /v1/provider taken verbatim from a real record, labelled as an example with its last-verified date. Use it to see the shape and depth of paid data before paying.
get_providerWhat exactly does this provider support, where is it licensed and what does it charge?No findings
Why it is in this group
- The name "get_provider" says "get": a word for reading.
Description, as the server wrote it
What exactly does this provider support, where is it licensed and what does it charge? Paid ($0.01 USDC): Full cited record for one provider: stablecoin rails, corridors, licences, published fees, coverage, developer and agent-payment support. Every fact has source URL, retrieval date, quote and confidence. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/provider. Pay with your own x402/MPP client and retry that URL.
get_tokenWhat are the symbol, name, decimals, contract address and issuer of this stablecoin on this chain?No findings
Why it is in this group
- The name "get_token" says "get": a word for reading.
Description, as the server wrote it
What are the symbol, name, decimals, contract address and issuer of this stablecoin on this chain? Paid ($0.001 USDC): Cited stablecoin token facts from a prepared dataset (USDC, EURC, USDT, PYUSD, DAI on the chains /v1/chain covers, where a permissively licensed source lists them): symbol, name, decimals, contract address, chain, issuer, each with a source citation and license. Fields not established from a source are the string "unknown". Malformed input and tokens not in the dataset return 400/404 and are never charged. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/token. Pay with your own x402/MPP client and retry that URL.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
