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.

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
69/69 tools missing one or more hints — get_tvl (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_apr_rewards (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_apr_by_key (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +66 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
47/69 tool handlers declare input schemas (68%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
35/69 tools referenced in tests (51%)
Write tests that reference each tool by name so every tool has at least one test.
Dev dependencies
16 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
