overleaf-claude-mcp (MarvelCollin/overleaf-claude-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.
MCP server that connects Claude to Overleaf. Read, edit, compile and restore LaTeX projects on the free tier.
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.

Tool annotations
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
25/25 tools missing one or more hints — overleaf_compile (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); overleaf_compile_log (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); overleaf_download_pdf (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 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
23/25 tool handlers declare input schemas (92%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
5 child_process/subprocess calls in production code — runs shell commands (src/auth/browsers.ts:93, src/auth/browsers.ts:110, src/auth/browsers.ts:120)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
