Source:: github.com/ai-integr8tor/exa-mcp-server
Version:: 3.2.1
Author:: Exa Labs
Provenance:: Found by crawling (provenance, not a security rating)

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 osv-scanner. The composite score alone does not reflect this — read the per-scanner reports below.

npm: exa-mcp-server @ 3.2.1, 0 findings

Install

Choose your runtime: the CLI writes the mcpServers config entry for that target.

nerlo install --target claude-code -- exa-mcp-server

Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.

Your view:

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.

AI review of these findings

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.

Upheld as real: 182
Dismissed as false positives: 8
Not reviewed: 0

Out of 190 findings across every scanner that examined this package. None of the 1 finding rated critical by their scanner were dismissed.

Why those were dismissed

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.

In installed code — never dismissed

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.

What the review concluded

Critical and high-severity vulnerabilities found in installed code.

The artifact contains a critical vulnerability in a dependency, which could enable remote code execution. Multiple high-severity findings indicate potential for network egress to internal services, credential access through marketplace interactions, and issues with state management in core components. These findings are present in package configuration files and application source code.

Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
