Loading the registry…
Streamable HTTP (stateless) reference implementation for MCP learning edition.
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.
1 critical finding reported by agent-audit-kit. The composite score alone does not reflect this — read the per-scanner reports below.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- calculator-learning-demo-stateless
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
5 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 32 findings across every scanner that examined this package. None of the 1 finding rated critical by their scanner were dismissed.
Not reviewed is not the same as clean. Those 4 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
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.
19 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: AAK-MCP-STATELESS-001, AAK-MCP-018, DATA_EXFIL_JS_NETWORK · Files: src/tests/test-utils.ts, src/tests/stateless-integration.test.ts, src/tests/stateless-server.test.ts and 2 more · reported by agent-audit-kit, cisco-skill-scanner
4 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.
Rules: AAK-AGENT-002, agents-claude-md-url-exec-2105 · Files: CLAUDE.md · reported by agent-audit-kit, agentshield
The model could have called any of these a false positive and did not.

Critical DNS rebinding vulnerability detected.
The artifact exhibits a critical DNS rebinding vulnerability in `src/stateless-production-server.ts`, potentially enabling network egress and access to internal services. A high-severity DNS rebinding risk is also present in `package.json`. Additionally, several medium and low severity findings relate to data handling and third-party OAuth integration.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
