Bug Reports

The official github-mcp-server doesn’t work with 1.0.0

Testing local works with jsonrpc

$ docker run -i --rm -e GITHUB_PERSONAL_ACCESS_TOKEN="<key>" ghcr.io/github/github-mcp-server
$ {"jsonrpc": "2.0","id": 1,"method": "tools/call","params": {"name": "get_me","arguments": {}}}

Gives expected response

Cursor MCP does not work

Server shows active and tools enabled but the model has no idea of the tools (other MCPs work)

Same here

Think I figured it out, if you’re using custom Modes, the MCP option doesn’t auto-add new servers (even if you have MCP checkmarked), you need to manually check each new server for each mode

Hi - I’m new to curse and to MCP in general - I appear to be getting the same behavior. I’m trying to set up the official github mcp server on curser 1.0. Can you provide a little bit more detail around what custom modes mean and how I can check for those? I’ve been fighting to get this running for a few days now. Thanks!

i have the same problem

if it’s the same issues with me, when you have a chat dialog there will be the modes (Agent, Ask, et cetera), but if you’re not familiar with this then it’s probably not the issue as defaults son’t allow you to customize what tools the model can use
