MCP Documentation Crawler (codecracker2020/mcp-server-crawler) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
This server crawls documentation sites and provides search and page-retrieval tools through MCP, enabling users to query indexed documentation content.
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
4/4 tools missing one or more hints — crawl_documentation (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_documentation (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_documentation_page (missing: readOnlyHint, destructiveHint, 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 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, 2 high severity in production deps — @modelcontextprotocol/sdk@1.24.1 (high), @modelcontextprotocol/sdk@1.24.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
