Loading the registry…
Remote MCP connector for the RealtyStack API — U.S. real-estate data via RentCast: property records search + single-record lookup, AVM sale-value and long-term-rent estimates with comparables, and active sale/rental listings — exposed as MCP tools for Claude/ChatGPT/any MCP client. The wrapped data is queried through RealtyStack's flat /v1 JSON contract; outbound calls carry a server-side RapidAPI proxy secret so this free tier stays a discovery channel over the metered upstream.
The publisher performed an authenticated act of publication — proving control of a namespace in the official MCP registry, or appearing in a first-party catalogue an operator curates. That establishes WHO published it. It is not a security finding, and attested artifacts carry Flagged verdicts too.
2 critical findings reported by agent-audit-kit, 1 of them in the installed artifact. 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 -- realtystack-mcp
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 11 findings across every scanner that examined this package. 1 of 2 findings rated critical by their scanner was 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.
1 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.

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 DNS rebinding and secret network egress detected.
The artifact exhibits a critical DNS rebinding vulnerability in `api/mcp.js`, which could permit bypassing same-origin policy. Additionally, it performs network egress of secrets from `/repo/lib/tools.js`. Other findings include potential third-party OAuth integration issues and general network egress capabilities.
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.
