Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
FIGMA_TOKEN"": "figd_your_token_here"FIGMA_WS_PORT3055 Loopback port for the plugin bridge. Change it if something else owns 3055; set the same number in the plugin window.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
8/8 tools missing one or more hints — figma_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); figma_run (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); figma_current_selection (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
No eval / new Function
1 eval() or new Function() call — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (server/test-bridge.js:16)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
1 secret/sensitive value flow into network calls (FIGMA_TOKEN → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
