Performance Analysis MCP Server
Collects page performance metrics using Playwright, CDP, and Lighthouse, and returns a normalized PerformanceReport.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
analyze_pageCollect page performance metrics for a public http(s) URL using Playwright and CDP.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Playwright downloads and installs browsers without verifying the authenticity of the SSL certificate
DEFAULT_URLThe HTTP server is available for local testing and non-MCP clients. You can provide a default URL via or pass a URL in each request.SAVE_REPORTS_DIRPORTAll four hints declared on every tool
1/1 tools missing one or more hints — analyze_page (missing: destructiveHint, idempotentHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool annotations match behaviour
1 read-only tool performs write/delete/exec — analyze_page (line 50: fs.promises.mkdir(saveDir, { recursive: true }))
Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/1 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 1 high severity in production deps — playwright@1.45.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
