Your Question

I am trying to add a new tool to the git server

Tool(
    name=GitTools.CREATE_BRANCH,
    description="Creates a new branch from an optional base branch",
    inputSchema=GitCreateBranch.schema(),
),

When I run the inspector from the git server directory (/Users/mikegehard/workspace/aiDev/mcp-servers/src/git) using npx @modelcontextprotocol/inspector uv run mcp-server-git it connects just fine and I can see the new endpoint.

When I test it out via the inspector, it works as expected.

Now I'm trying to integrate it with my Claude desktop app.

Here is the claude_desktop_config.json:

{
  "mcpServers": {
    "git": {
      "command": "uv",
      "args": [
        "run",
        "mcp-server-git",
        "--repository",
        "/Users/mikegehard/workspace/aiAssistedAgile/aiAssistedAgileAgents"
      ],
      "cwd": "/Users/mikegehard/workspace/aiDev/mcp-servers/src/git"
    }
}

which I got from Claude desktop app via the file server and the working git server. Dogfooding for the win! :-)

When I run Claude desktop, I get the following error:

==> /Users/mikegehard/Library/Logs/Claude/mcp-server-git.log <==
error: Failed to spawn: `mcp-server-git`
  Caused by: No such file or directory (os error 2)

I have narrowed the directory not found to the "cwd" in the JSON I think.

Any other tips for troubleshooting why this isn't working in the Claude app (which is the latest) but it works in the inspector?

Thanks!

I have recently modified the json to look like this based on another "getting started" video:

 "git": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/mikegehard/workspace/aiDev/mcp-servers/src/git",
        "run",
        "mcp-server-git"
      ]
    },

Using the above I now see my new tool in the Claude desktop application.

I will add a development note to the git server README to record this.
