GitCaddy MCP Server

A Model Context Protocol (MCP) server that enables AI assistants like Claude to interact directly with your GitCaddy instance.

Features

• Query Runners - List runners, check status, view capabilities (OS, tools, disk space)
• Monitor Workflows - List runs, get job details, view logs
• Manage Releases - List releases, get assets, check download counts
• AI Learning - Query error patterns, report solutions, help other AIs learn
• AI-Friendly - Structured JSON responses designed for AI consumption

Quick Start

1. Download

Download the latest binary from Releases.

2. Configure Claude Code

Add to your Claude Code settings:

Option A: Command line arguments

{
  "mcpServers": {
    "gitcaddy": {
      "command": "/path/to/gitcaddy-mcp-server",
      "args": ["--url", "https://git.marketally.com", "--token", "YOUR_API_TOKEN"]
    }
  }
}

Option B: Environment variables

{
  "mcpServers": {
    "gitcaddy": {
      "command": "/path/to/gitcaddy-mcp-server",
      "env": {
        "GITCADDY_URL": "https://git.marketally.com",
        "GITCADDY_TOKEN": "your-token-here"
      }
    }
  }
}

3. Use It

Ask Claude things like:

• "What runners are online?"
• "Show me the latest workflow runs for gitcaddy/act_runner"
• "Why did run #77 fail?"
• "What assets are in the v0.3.6 release?"
• "Are there any known solutions for NETSDK1147?"
• "Diagnose why job 456 failed"

Available Tools

Runner & Workflow Tools

Tool	Description
list_runners	List all runners with status, capabilities, disk space

report_solution_success	Mark a solution as successful (improves ranking)
get_compatibility_matrix	See what project types work on which runners
diagnose_job_failure	Auto-analyze failed job logs and suggest solutions

AI Learning System

GitCaddy includes a collaborative AI learning system. When you encounter and fix CI/CD errors, you can report your solutions to help other AI assistants:

AI encounters error -> get_error_patterns -> finds solution -> applies fix
                                                  |
                                                  v
                                        report_solution_success
                                        (improves ranking)

AI finds NEW solution -> report_error_solution -> stored in database
                                                  |
                                                  v
                                        Other AIs can now find it

Example: Diagnosing a Failed Build

User: "Why did job 789 fail?"

Claude uses: diagnose_job_failure(owner="myorg", repo="myapp", job_id=789)

Response:
{
  "extracted_errors": ["NETSDK1147", "XA5300"],
  "diagnoses": [
    {
      "pattern": "NETSDK1147",
      "diagnosis": "The .NET MAUI Android workload is not installed",
      "solution": "Install the workload: dotnet workload install maui-android",
      "success_rate": 94.5
    }
  ]
}

Building from Source

git clone https://git.marketally.com/gitcaddy/mcp-server.git
cd mcp-server
go build -o gitcaddy-mcp-server .

Cross-compile for all platforms

# Linux
GOOS=linux GOARCH=amd64 go build -o gitcaddy-mcp-server-linux-amd64 .

# macOS Intel
GOOS=darwin GOARCH=amd64 go build -o gitcaddy-mcp-server-darwin-amd64 .

# macOS Apple Silicon
GOOS=darwin GOARCH=arm64 go build -o gitcaddy-mcp-server-darwin-arm64 .

Architecture

+-------------+     stdio      +------------------+     HTTP      +-------------+
| Claude Code | <------------> | gitcaddy-mcp     | <-----------> |  GitCaddy   |
|  (AI Tool)  |   JSON-RPC     |   (This binary)  |  /api/v2/mcp  |   Server    |
+-------------+                +------------------+               +-------------+

The MCP server:

1. Receives JSON-RPC requests over stdio from Claude Code
2. Forwards them to GitCaddy's /api/v2/mcp endpoint
3. Returns responses back to Claude Code

Configuration Options

Flag	Env Variable	Description
--url	GITCADDY_URL	GitCaddy server URL (required)
--token	GITCADDY_TOKEN	API token for authentication
--debug	-	Enable debug logging to stderr

Note: GITEA_URL and GITEA_TOKEN are also supported for backwards compatibility.

Obtaining an API Token

1. Go to your GitCaddy instance -> Settings -> Applications
2. Generate a new token with appropriate scopes
3. Copy the token and use it in your configuration
