MCP Submission Check
Claude connectorCommunityCheck your MCP tools and listing against Claude's connector directory rules before you submit.
Paste a tool's name, title, annotations and description, and get back every problem that would block review: missing titles or read-only hints, names over 64 characters, catch-all tools mixing GET and POST, hidden characters, and wording that instructs the model. It also checks your listing text against the form limits (200-character one-liner, 2,000-character description, 5 categories) and returns the full submission checklist. Read-only, no account needed.
MCP Submission Check is #7,499 of 11,065 Claude connectors by popularity, up 165 places in a week.
