## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-24.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (8)

### `payability_verdict` (~55 tokens)

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.

Input parameters:

- `url` (string, required)

### `find_endpoints` (~131 tokens)

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.

Input parameters:

- `limit` (integer)
- `network` (string)
- `query` (string, required)
- `sort` (string)

### `catalogue_stats` (~38 tokens)

Catalogue stats

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

### `host_summary` (~58 tokens)

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.

Input parameters:

- `host` (string, required)

### `x401_status` (~24 tokens)

x401 status

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

### `drift_status` (~42 tokens)

Drift status

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

Input parameters:

- `host` (string)

### `verify_signature` (~326 tokens)

Verify signature

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.

Input parameters:

- `response_json` (string, required)
- `service` (string)

### `reports` (~18 tokens)

Weekly reports

Published weekly payability reports (from the signed manifest).

org.nsgoods/nsgoods-workbench-mcp scores 71 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the org.nsgoods/nsgoods-workbench-mcp server expose?

org.nsgoods/nsgoods-workbench-mcp exposes 8 tools: payability_verdict, find_endpoints, catalogue_stats, host_summary, x401_status, and 3 more. Their descriptions and schemas cost roughly 692 tokens of context every time the server is loaded.

### Does the org.nsgoods/nsgoods-workbench-mcp server require authentication?

No. We connected to org.nsgoods/nsgoods-workbench-mcp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
