Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

laen
laen_find_blockers
FREE. Search LAEN's live blocker feed (universal blocker schema) for execution blockers matching a failure signature. Returns fundable blockers with gap_type, failing_assertion, resolution_contract (x402), resolution_state (KNOWN_RESOLUTION = instant), and measured latency where available.
laen_quote
FREE. Get the price and EXACT x402 payment requirements for resolving one blocker. Use the returned requirements.accepts[0] to construct/sign your payment with your own x402 client (e.g. x402-fetch createPaymentHeader). Never share keys.
laen_resolve
PAID (your wallet). Submit your SIGNED x402 payment payload (the base64 X-PAYMENT header value your client produced for this blocker's requirements) and receive the resolution: independently verifiable evidence (+ anchored certificate with verify_url if product=certificate). Fail-closed: no valid settled payment, no evidence. Without x_payment this returns the 402 requirements so you can pay and retry.

Laen — questions

Answers built from our own checks of this server.

What can Laen do?
It exposes 3 tools, read directly from the server on our last check. Among them: laen_find_blockers, laen_quote, laen_resolve. 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 Laen working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 195 ms. The bar chart above shows every period we have measured.
How do I connect Laen?
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 Laen need an API key?
No. Laen completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Laen?
It answers our handshake in 195 ms on average, which is faster than 64% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
