Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security86
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability69
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 346 tokens (~86/item across 4 items; 4 tools + 0 resources), lean.Pass
  • 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 Coverage94
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 83% of tool parameters carry a description.Partial
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Changelog

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

  • 3 Aug 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools — 4 exposed · ~346 tokens

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.

Tool Tokens
costwright_certify ~121

Issue a tamper-evident, Ed25519-signed budget certificate for an agent repo (re-run server-side, logged to a public transparency log). Same input as costwright_check plus an optional label. Returns the cert_id, the signed certificate and a verify_url. Use to produce an auditable proof of a workflow's worst-case spend ceiling.

NameTypeReqDescription
labelstringOptional human label for the certificate.
policystring
repo_pathstringyesAbsolute path to the local Python repo/directory to certify.

No output schema declared.

No examples provided.

costwright_check ~126

Statically analyze an LLM-agent repo (LangGraph / CrewAI / OpenAI-Agents-SDK) for runaway-budget risk WITHOUT running it. Builds a .py-only archive of the given local path and returns a worst-case budget summary: counts of certifiable / default_dependent / non_certifiable / runaway graph units and a pass|fail verdict. Use before deploying a workflow to catch missing token caps and while-True runaway drivers.

NameTypeReqDescription
policystringAnalysis policy.
repo_pathstringyesAbsolute path to the local Python repo/directory to analyze.

No output schema declared.

No examples provided.

costwright_pubkey ~37

Fetch costwright's active Ed25519 public keys (PEM) for offline signature verification of any certificate (public, no key).

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

costwright_verify ~62

Verify a previously issued costwright certificate by id (public, no key). Returns its state (valid|expired|revoked|signature_invalid), whether the signature checks out, and the certified result.

NameTypeReqDescription
cert_idstringyesThe certificate id to verify.

No output schema declared.

No examples provided.
