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.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
mcp-handler has a tool response leak across concurrent client sessions ('Race Condition')
Next.js has a Middleware / Proxy bypass in App Router applications via segment-prefetch routes
Next.js has a Middleware / Proxy bypass in App Router applications via segment-prefetch routes - Incomplete Fix Follow-Up

ANTHROPIC_API_KEYBRAVE_API_KEYCRON_SECRETELEVENLABS_API_KEYFAL_KEYX402_FACILITATOR_URLTool 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
33/33 tools missing one or more hints — generate_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); take_screenshot (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); html_to_markdown (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +30 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
32/33 tool handlers declare input schemas (97%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
24/33 tool handlers wrap calls in try/catch (73%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
6 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 10 high severity in production deps — @modelcontextprotocol/sdk@1.25.2 (high), mcp-handler@1.0.7 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
1/16 production deps stale: ml-random-forest@2022-05-09 (4.2y)

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.
