A Model Context Protocol (MCP) server implementation for CircleCI, enabling natural language interactions with CircleCI functionality through MCP-enabled clients
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
3 critical findings reported by cisco-skill-scanner, osv-scanner, 1 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
npm: @circleci/mcp-server-circleci @ 0.20.0, 0 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- @circleci/mcp-server-circleci
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
8 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 133 findings across every scanner that examined this package. 2 of 3 findings rated critical by their scanner were among the dismissals.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
8 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.
Rules: YARA_credential_harvesting_generic, DATA_EXFIL_JS_FS_ACCESS · Files: /repo/src/tools/findUnderusedResourceClasses/handler.test.ts, /repo/src/lib/file-output/safePaths.test.ts, /repo/src/lib/pipeline-job-logs/getJobLogs.test.ts · reported by cisco-skill-scanner
3 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.
Rules: MANIFEST_INVALID_NAME, SOCIAL_ENG_VAGUE_DESCRIPTION, MANIFEST_MISSING_LICENSE · Files: /repo/.github/PULL_REQUEST_TEMPLATE/SKILL.md · reported by cisco-skill-scanner
These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Critical vulnerability and multiple high-severity risks identified.
The artifact contains a critical vulnerability in a dependency listed in `pnpm-lock.yaml`. Additionally, it exhibits high-severity risks including potential DNS rebinding in `package.json`, handling of secrets in `src/lib/auth/resolveToken.ts` and `src/lib/telemetry/config.ts`, and network egress with secrets in `src/lib/telemetry/metrics.ts`. The artifact also uses the Anthropic SDK in `src/index.ts` and `src/transports/stdio.ts`, which typically involves network communication.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Showing 25 of 44; the rest are in the per-scanner reports above.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
