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.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Happy DOM: VM Context Escape can lead to Remote Code Execution
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
Happy DOM ECMAScriptModuleCompiler: unsanitized export names are interpolated as executable code
Happy DOM's fetch credentials include uses page-origin cookies instead of target-origin cookies
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
5/5 tools missing one or more hints — init-browser (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-full-dom (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get-screenshot (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 more. 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 inputs are validated
Only 2/5 tool handlers declare input schemas (40%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
1 critical, 6 high severity in production deps — happy-dom@17.4.4 (critical), @modelcontextprotocol/sdk@1.7.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
4/24 production deps abandoned (no release in 2+ years): react-contenteditable@2023-02-28 (3.5y), tailwindcss-animate@2023-08-28 (3y), @skorotkiewicz/snowflake-id@2024-02-06 (2.5y)

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.
