MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out
Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 15 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 5048 tokens (~240/item across 21 items; 18 tools + 3 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 18 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 19 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the FiatDock MCP server?
FiatDock is a hosted endpoint at https://fiatdock.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
address_intel Address intelligence on Base ($0.005) ~291
PAID ($0.005 USDC via x402). Enrich ANY Base address in one call before you trust it: EOA vs contract (and whether it's an ERC-20, with its name/symbol/decimals), account nonce, ETH + USDC balance, and a KEYLESS GoPlus security verdict (phishing / sanctioned / mixer / money-laundering / blacklist and more) — the loop input for triaging a counterparty, payout target or approval spender. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. A bad address returns 400; if Base RPC or GoPlus is unavailable it returns 502 — neither is charged.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | A 40-hex EVM address (0x…) on Base to enrich |
| payment | string | – | Base64 of a single x402 v2 PaymentPayload (EIP-3009 transferWithAuthorization on Base USDC). OMIT it on the first call: the 402 you get back carries `howToPay.payloadTemplate` — the exact envelope to… |
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The queried address |
| asOf | string | yes | ISO 8601 read time |
| ethBalance | string | yes | Native ETH balance as a decimal string |
| isContract | boolean | yes | true if the address has bytecode on Base |
| isErc20 | boolean | yes | true if it is an ERC-20 token contract |
| network | string | yes | Chain read (always base) |
| nonce | number | yes | Outgoing transaction count (account nonce) |
| security | object | yes | Keyless GoPlus address-security verdict |
| summary | string | yes | One-line human-readable verdict |
| token | – | yes | ERC-20 identity when isErc20, else null |
| type | string | yes | eoa | contract | erc20_contract |
| usdcBalance | string | yes | USDC balance as a decimal string |
No examples provided.
block_number Base block height ($0.001) ~198
PAID ($0.001 USDC via x402). The latest Base block number plus its timestamp — a freshness/liveness probe for agents that need to know the chain head. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. On any RPC failure the call returns 4xx/5xx and is NOT charged.
| Name | Type | Req | Description |
|---|---|---|---|
| payment | string | – | Base64 of a single x402 v2 PaymentPayload (EIP-3009 transferWithAuthorization on Base USDC). OMIT it on the first call: the 402 you get back carries `howToPay.payloadTemplate` — the exact envelope to… |

| network | string | yes | Chain read (always base) |
| timestamp | number|null | yes | Unix seconds of the latest block (null if unavailable) |
| timestampIso | string|null | yes | ISO 8601 of the latest block time (null if unavailable) |
No examples provided.
call_service Call a marketplace service ~309
Invoke a listed FiatDock service. PAID listings go THROUGH the gateway (POST /s/:id) so the non-custodial split is enforced — normally TWO payments (99% seller + 1% FiatDock), or ONE full-price payment to the seller during that seller's first-month 0% launch window. TO BUY: call once WITHOUT `payment` to get the 402 challenge and step-by-step instructions, sign it with your own wallet, then call again with the same id/args plus `payment` set to the base64 x402 payload — the gateway settles on-chain directly to the seller and returns their response. No wallet? `npx fiatdock-mcp` with AGENT_PRIVATE_KEY signs automatically. FREE / first-party listings are forwarded to their real MCP endpoint directly (no payment). Pass the service's expected request body as `args`.
| Name | Type | Req | Description |
|---|---|---|---|
| args | object | – | JSON payload to send to the service (e.g. an MCP JSON-RPC request body) — shape is defined by that service |
| id | string | yes | Listing id (svc_…) to invoke, from search_services |
| payment | string | – | Base64 x402 v2 PaymentPayload signed by YOUR wallet, satisfying every entry in the 402's `accepts`. Omit on the first call to receive the challenge; send it on the second call to complete the purchas… |
| Name | Type | Req | Description |
|---|---|---|---|
| ok | boolean | yes | true when the underlying service returned a 2xx |
| result | – | – | The service's response body — parsed JSON when it returned JSON, otherwise the raw text |
| routedThroughGateway | boolean | yes | true if PAID (settled 99% seller / 1% FiatDock via /s/:id); false if FREE/first-party direct |
| service | string | yes | Listing id that was invoked |
| status | number | yes | HTTP status returned by the service (or the gateway) |
No examples provided.
create_offramp_session Create off-ramp session (USDC → bank) ~683
Convert the agent's USDC to fiat in the owner's OWN bank account. Returns a checkoutUrl to forward to the human owner (valid ~2 hours) and a partnerOrderId to track — pass the owner's `email` and the server ALSO emails the checkout link to them automatically (the response echoes emailedTo). Paid endpoint ($0.01 USDC via x402) — without payment this returns the 402 challenge; use the fiatdock-mcp npm package with AGENT_PRIVATE_KEY for automatic payment. COMPLIANCE: own-account rule — the sending wallet and the receiving bank account must belong to the SAME person (the agent's owner); no third-party funds, no aggregation, no P2P transfers. 18+; served worldwide via our licensed provider across ~160 countries — EUR bank transfer in the SEPA zone (incl. Portugal), card/Apple Pay/Google Pay elsewhere — excluding US persons, sanctioned countries and the UK (NOT the UK). Crypto is volatile; not investment advice.
