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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
@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
MCP Inspector is Vulnerable to Potential Command Execution via XSS When Connecting to an Untrusted MCP Server
HASS_ACCESS_TOKEN(required): Long-lived access token for Home Assistant. The server will not start without this.HASS_URL(required): The URL of your Home Assistant instance. Example: https://your-home-assistant.local:8123 (default in code: http://localhost:8123)LIMIT_RESOURCESSet to a number to limit the number of resources returned by the server. Default: unlimited.RESOURCES_TO_TOOLSSet to true to enable mapping resources to tools. Default: false.USE_MOCKSPORTAll four hints declared on every tool
18/18 tools missing one or more hints — delete-automation (missing: destructiveHint, idempotentHint, openWorldHint); update-automation-by-entity-id (missing: destructiveHint, idempotentHint, openWorldHint); update-rest-automation-by-rest-id (missing: destructiveHint, idempotentHint, openWorldHint), +15 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 test coverage
Only 1/18 tools referenced in tests (6%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.17.3 (high), @modelcontextprotocol/sdk@1.17.3 (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.

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.
