Available tools 8

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

catalogue

catalogue_stats

Size and health of the x402 catalogue as of the latest full scan: resources, hosts, verdict counts, and payable endpoints per network.

drift

drift_status

Verdict changes between the two latest full scans (catalogue wide, or for one host), plus the declared model drift watch.

endpoints

find_endpoints

Search the catalogue by host or URL substring. Returns up to `limit` endpoints with their latest verdict, plus the total match count. Use this first when you do not know the exact resource URL. Optional network filter (for example eip155:8453 or solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) and sort=price for the cheapest first.

host

host_summary

Summary for a host (no time series): first/last seen, current verdict mix, n_resources, total verdict changes, gone_since if absent from the latest full scan, and a small resources_sample.

payability

payability_verdict

Latest payability observation for one exact resource URL (path and query included), with the meaning of the verdict, remediation if it cannot be paid, and the per-network options seen.

reports

reports

Published weekly payability reports (from the signed manifest).

verify

verify_signature

Offline EIP-191 verify of a signed nsgoods response. Strips preview/demo post-sign fields, canonicalises (JCS, trying both ASCII escaping modes), recovers the signer, and checks it against the published manifest signers.

x401

x401_status

Current x401 emitter adoption across the scanned catalogue (from the daily watcher).

How do I connect Nsgoods Workbench MCP?

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 Nsgoods Workbench MCP need an API key?

No. Nsgoods Workbench MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Nsgoods Workbench MCP?

It answers our handshake in 447 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
