Self-hosted MCP server for searching and discovering books using Anna's Archive and Goodreads datasets, enabling full-text search, ISBN/md5 lookup, similarity matching, and optional download URL retrieval.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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
16/16 tools missing one or more hints — search_books (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_goodreads (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_similar (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 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
15/16 tool handlers declare input schemas (94%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/16 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
7/16 tools referenced in tests (44%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
3 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, 4 high severity in production deps — drizzle-orm@0.45.1 (high), fast-xml-parser@5.3.7 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
3 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
