Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. 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.
Hono: app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths
Hono: Cookie helper does not sanitize sameSite and priority, allowing Set-Cookie injection
Hono: JWT middleware accepts any Authorization scheme, not only Bearer
Hono: IP Restriction bypasses static deny rules for non-canonical IPv6
js-yaml has prototype pollution in merge (<<)

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
15/15 tools missing one or more hints — obsidian_validate_format (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); obsidian_update_note (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); obsidian_search_replace (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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
13/15 tool handlers declare input schemas (87%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 4/15 tool handlers wrap calls in try/catch (27%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
24 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dependency freshness
2/22 production deps stale: json5@2023-03-04 (3.3y), partial-json@2024-05-14 (2.1y)
