Hey,

To ensure that only working servers are listed, we're updating our listing requirements.

Please complete the following steps:

1. Ensure your server is listed on Glama. If it isn't already, submit it at https://glama.ai/mcp/servers and verify that it passes all checks (note: you must add Dockerfile directly to Glama. For checks to pass, we only need the server to start and respond to introspection requests).

2. Update your PR by adding a Glama score badge after the server description, using this format:

[![OWNER/REPO MCP server](https://glama.ai/mcp/servers/OWNER/REPO/badges/score.svg)](https://glama.ai/mcp/servers/OWNER/REPO)

Replace OWNER/REPO with your server's Glama path.

If you need any assistance, feel free to ask questions here or on Discord.

P.S. If your server already has a hosted endpoint, you can also list it under https://glama.ai/mcp/connectors.
