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 Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 927 tokens (~115/item across 8 items; 8 tools + 0 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 Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 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 org.nsgoods/nsgoods-workbench-mcp server?
org.nsgoods/nsgoods-workbench-mcp is a hosted endpoint at https://mcp.nsgoods.org/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 →
catalogue_stats Catalogue stats ~38
Size and health of the x402 catalogue as of the latest full scan: resources, hosts, verdict counts, and payable endpoints per network.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
drift_status Drift status ~42
Verdict changes between the two latest full scans (catalogue wide, or for one host), plus the declared model drift watch.
| Name | Type | Req | Description |
|---|---|---|---|
| host | string | – | – |
No output schema declared.
No examples provided.
find_endpoints Find endpoints ~131
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| network | string | – | – |
| query | string | yes | – |
| sort | string | – | – |
No output schema declared.
No examples provided.
host_summary Host summary ~58
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.
| Name | Type | Req | Description |
|---|---|---|---|
| host | string | yes | – |
No output schema declared.
No examples provided.
payability_verdict Payability verdict ~55
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.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | – |
No output schema declared.
No examples provided.
reports Weekly reports ~18
Published weekly payability reports (from the signed manifest).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
verify_signature Verify signature ~326
Offline EIP-191 verify of a signed nsgoods response. Identifies the service from the manifest (or the optional `service` arg), strips exactly that service's post-sign fields, canonicalises (JCS, both ASCII modes), recovers the signer and checks it against the published manifest signers. Reproduction-attestation (JCS/byte-length) and envelope (signer/signature, components) shapes are reported as unsupported_shape, not verified here. Refusals carry a distinct status: malformed_signature (signature is not a 65-byte 0x-prefixed hex string), schema_rejected (the body carries a signed_by/signature pair but fails the required field shape for every service the claimed signer covers; recovery was not attempted, checked is false, reasons lists the failed candidates), signature_mismatch (well-formed but recovers a different address than signed_by under every candidate service recipe of this signer), no_flat_recipe (signed_by is a manifest signer but every service it covers uses an envelope shape, so there is no flat recipe to check; recovery was not attempted, checked is false), unknown_signer (signed_by is not a manifest signer; recovery was not attempted, checked is false), unsupported_shape, or the no-signed_by/signature-pair case. checked is true only when EIP-191 recovery actually ran; every other refusal reports checked false.
| Name | Type | Req | Description |
|---|---|---|---|
| response_json | string | yes | – |
| service | string | – | – |
No output schema declared.
No examples provided.
x401_status x401 status ~24
Current x401 emitter adoption across the scanned catalogue (from the daily watcher).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
