:lady_beetle: Provide a clear description of the bug

When using the github-mcp-server the add_pull_request_review_comment_to_pending_review tool is not “seen” by the AI agent.

I did ensure that the tool is exposed by the mcp server by listing tools using mcptools

$ GITHUB_PERSONAL_ACCESS_TOKEN=YOUR_TOKEN mcptools tools github-mcp-server stdio|grep -E '^\w+'|grep add_pull_request_review_comment_to_pending_review
add_pull_request_review_comment_to_pending_review(body:str, owner:str, path:str, pullNumber:num, repo:str, subjectType:str, [line:num], [side:str], [startLine:num], [startSide:str])

:counterclockwise_arrows_button: Explain how to reproduce the bug

  1. Install github-mcp-server, see GitHub - github/github-mcp-server: GitHub's official MCP Server. Use the following mcp.json configuration
{
    "mcpServers": {
        "github": {
            "command": "/path/to/github-mcp-server",
            "args": [
                "stdio",
                "--toolsets",
                "pull_requests"
            ],
            "env": {
                "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_TOKEN_HERE"
            }
        }
    }
}
  1. Ask agent to list available tools with this prompt List raw names of all tools available to you
  2. One can assess that the add_pull_request_review_comment_to_pending_review tool is not available to the AI agent.

NOTE: When shortening the name of this tool to add_pull_request_review_comment the tool was then available to the AI agent.
