## Standard input/output server

```sh
go run cmd/github-mcp-server/main.go stdio
```

E.g:

Set the PAT token in the environment variable and run:

```sh
script/get-me
```

And you should see the output of the GitHub MCP server responding with the user information.

```sh
GitHub MCP Server running on stdio
{
  "jsonrpc": "2.0",
  "id": 3,
  "result": {
    "content": [
      {
        "type": "text",
        "text": "{\"login\":\"juruen\",\"id\" ... }
      }
    ]
  }
}

```

## i18n / Overriding descriptions

The descriptions of the tools can be overridden by creating a github-mcp-server.json file in the same directory as the binary.
The file should contain a JSON object with the tool names as keys and the new descriptions as values.
For example:

```json
{
  "TOOL_ADD_ISSUE_COMMENT_DESCRIPTION": "an alternative description",
  "TOOL_CREATE_BRANCH_DESCRIPTION": "Create a new branch in a GitHub repository"
}
```

You can create an export of the current translations by running the binary with the `--export-translations` flag.
This flag will preserve any translations/overrides you have made, while adding any new translations that have been added to the binary since the last time you exported.

```sh
./github-mcp-server --export-translations
cat github-mcp-server.json
```

You can also use ENV vars to override the descriptions. The environment variable names are the same as the keys in the JSON file,
prefixed with `GITHUB_MCP_` and all uppercase.

For example, to override the `TOOL_ADD_ISSUE_COMMENT_DESCRIPTION` tool, you can set the following environment variable:

```sh
export GITHUB_MCP_TOOL_ADD_ISSUE_COMMENT_DESCRIPTION="an alternative description"
```

## Testing on VS Code Insiders

First of all, install `github-mcp-server` with:

```bash
go install ./cmd/github-mcp-server
```

Make sure you:

1. Set your `GITHUB_PERSONAL_ACCESS_TOKEN` environment variable and ensure VS Code has access to it.
2. VS Code Insiders has access to the `github-mcp-server` binary

Go to settings, find the MCP related settings, and set them to:

```json
{
  "mcp": {
    "inputs": [],
    "servers": {
      "mcp-github-server": {
        "command": "path-to-your/github-mcp-server",
        "args": ["stdio"],
        "env": {}
      }
    }
  }
}
```

In `Copilot Edits`, you should now see an option to reload the available `tools`.
Reload, and you should be good to go.

Try something like the following prompt to verify that it works:

```
I'd like to know more about my GitHub profile.
```

## TODO

Lots of things!

Missing tools:

- push_files (files array)
- list_issues (labels array)
- update_issue (labels and assignees arrays)
- create_pull_request_review (comments array)

Testing

- Integration tests
- Blackbox testing: ideally comparing output to Anthropic's server to make sure that this is a fully compatible drop-in replacement.

And some other stuff:
