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
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default

CPANEL_MCP_ALLOW_RAW_APIogólne wywołania API --allow-raw-api true\false falseCPANEL_MCP_CONFIGplik połączeń --config PATH wymaganyCPANEL_MCP_READONLYtylko odczyt --readonly true\false trueAll four hints declared on every tool
4/4 tools missing one or more hints — healthcheck (missing: destructiveHint, openWorldHint); list_connections (missing: destructiveHint, openWorldHint); cpanel_uapi_call (missing: readOnlyHint, idempotentHint, openWorldHint), +1 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
3/4 tool handlers declare input schemas (75%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/4 tool handlers wrap calls in try/catch (25%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/4 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, 7 high severity in production deps — @modelcontextprotocol/sdk@1.17.5 (high), @modelcontextprotocol/sdk@1.17.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
