Feishu-MCP (cso1z/feishu-mcp) 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.
Provides access to Feishu (Lark) documents for AI-driven coding tools like Cursor, Windsurf, and Cline based on Model Context Protocol implementation.
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.

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
20/20 tools missing one or more hints — batch_update_feishu_block_text (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); batch_create_feishu_blocks (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); delete_feishu_document_blocks (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 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
Only 1/20 tool handlers declare input schemas (5%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 0/20 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (src/cli/commands/auth.ts:28)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 13 high severity in production deps — axios@1.7.9 (high), axios@1.7.9 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
