AI: Can't access RepoPrompt MCP even if it is correctly set up in Zed

[tzutoo]

Summary

Hi, I have configured the RepoPrompt MCP in Zed using the following json.

{
    "mcpServers": {
        "RepoPrompt": {
            "command": "/Users/me/RepoPrompt/repoprompt_cli",
            "args": []
        }
    }
}

// Zed settings
//
// For information on how to configure Zed, see the Zed
// documentation: https://zed.dev/docs/configuring-zed
//
// To see all of Zed's default settings without changing your
// custom settings, run `zed: open default settings` from the
// command palette (cmd-shift-p / ctrl-shift-p)
{
  "context_servers": {
    "RepoPrompt": {
      "env": {},
      "source": "custom",
      "enabled": true,
      "command": "/Users/me/RepoPrompt/repoprompt_cli",
      "args": []
    }
  },

And Zed successfully identified and list the tools of it.

However when I ask the agent to access and use the tools in RepoPrompt, it said it can't find the MCP named RepoPrompt and can't use any of the tool it provides.
