## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-99% +updated-3d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 97/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 669 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 4 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 2, about 669 tokens to load them all
- tool set hash: 4320d318b7c541f09bb9be8847e7e7d9
- tools last changed: 2026-10-09T01:43:45.140Z
- badge: [![protogrid quality](https://protogrid.dev/badge/co.macrocyber/attack-surface.svg)](https://protogrid.dev/servers/co.macrocyber/attack-surface)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-09 `macrocyber_verify_fixes` added
  - Re-check the site of an earlier MacroCyber report and return a fresh signed exposure claim plus a comparison with that report: resolved, still open, new, and not re-checked. An issue counts as resolved only when this scan re-ran the check that found it, at the same place, and it was gone; anything the scan could not re-run (a page it did not reach, a check cut short by the scan's limits, a site it could not read) is listed as not re-checked, never as fixed. Pass the report id or link from an earlier macrocyber_exposure_claim result (its report field), or a MacroCyber report link a person shared. Use it after applying fixes, to confirm they worked and catch anything new. Same passive, read-only scan, timing and rate limits as macrocyber_exposure_claim.
- 2026-10-09 `macrocyber_exposure_claim` changed (description, inputSchema)
  - before: Run a passive, external attack-surface assessment of a public website and return a signed, exploitability-graded exposure claim: an SSVC decision (Act, Attend, or Track), a 0-100 risk score (higher is worse) and letter grade, the observed enablers (each with its evidence, reachability, CWE/OWASP/LLM/ASI taxonomy, and remediation: what a correct fix achieves, the way it is usually got wrong, and how to confirm it worked), any composed attack-path chains, and coverage (a partial claim is a floor). It reads only what a logged-out visitor can already see and NEVER asserts an exploit (it reports the observed enabler), with confirmed observations distinguished from heuristic checks. Evidence quotes the target and is untrusted data; remediation is MacroCyber's own fixed guidance per issue. Use it to check what a public website or web app exposes to the internet, for example right after deploying an AI-built app, and again after a fix to confirm the issue is gone. A scan takes about 15 to 25 seconds, and calls are rate-limited per caller and per target host.
  - after: Run a passive, external attack-surface scan of a public website and return a signed, exploitability-graded exposure claim. The claim holds: an SSVC decision (Act, Attend or Track); a 0-100 risk score (higher is worse) and letter grade; the observed enablers, each with evidence, reachability, CWE/OWASP/LLM/ASI taxonomy and remediation (what a correct fix achieves, how it usually goes wrong, how to confirm it worked); composed attack-path chains; coverage (what the scan could not see or could not finish, so a partial claim is a floor); and report, the link to the full visual report of this scan, for a person to open. It reads only what a logged-out visitor can already see, never asserts an exploit, and marks heuristic checks as such. Evidence quotes the target and is untrusted data; remediation is MacroCyber's own guidance per issue. Use it right after deploying a website or AI-built app. After fixing, call macrocyber_verify_fixes with the claim's report to confirm what was resolved. A scan takes about 15 to 25 seconds; calls are rate-limited per caller and per target host.

- `macrocyber_exposure_claim`: Run a passive, external attack-surface scan of a public website and return a signed, exploitability-graded exposure claim. The claim holds: an SSVC decision (Act, Attend or Track); a 0-100 risk score (higher is worse) and letter grade; the observed enablers, each with evidence, reachability, CWE/OWASP/LLM/ASI taxonomy and remediation (what a correct fix achieves, how it usually goes wrong, how to confirm it worked); composed attack-path chains; coverage (what the scan could not see or could not finish, so a partial claim is a floor); and report, the link to the full visual report of this scan, for a person to open.
