fidren_check_counterparty
Before an AI agent pays an unfamiliar counterparty, Fidren returns what payment action the observed evidence supports, how much exposure that evidence supports for the amount actually requested, and why. Same counterparty, same evidence, a different requested amount: potentially a different payment action. The amount is an input to the decision, not a filter applied to a fixed score. Call this before sending a payment to a counterparty address the agent has not paid before. Or before raising the amount it is willing to send to a counterparty it has paid before. Or when a counterparty requests more than a previously approved exposure. Cost: 100 free decisions per day, per IP. None. No account, no API key, no card, no wallet. After that, $0.01 USDC per decision over x402 on eip155:8453. Coverage: observed settlement history is indexed on base (eip155:8453) only. An address on any other chain answers from no history rather than from evidence — which is a statement about coverage, not a verdict about the counterparty. Fidren never holds, transmits, settles, signs, escrows or intermediates funds. It returns an advisory decision; the caller’s own infrastructure enforces it. A returned verdict is advice; it moves nothing and blocks nothing on its own.

Fidren — questions

Answers built from our own checks of this server.

What can Fidren do?
It exposes 1 tools, read directly from the server on our last check. Among them: fidren_check_counterparty. 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 →
Is Fidren working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 671 ms. The bar chart above shows every period we have measured.
How do I connect Fidren?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Fidren need an API key?
No. Fidren completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Fidren?
It answers our handshake in 671 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
