Overview

MCP Midtrans is an MCP server that embeds the entire Midtrans payment gateway documentation as structured, searchable tools. When connected to an AI agent (Copilot, Claude, Cursor, etc.), the agent can:

• Look up any Midtrans API endpoint, request format, or response schema
• Get complete integration code for 15+ payment methods in 5 programming languages (Python, Django, Node.js, Go, PHP)
• Generate ready-to-use charge request JSON for any payment type
• Get webhook/notification handler code with signature verification
• Search across all documentation to find exactly what's needed

No API keys required — this server provides documentation only; it does not call the Midtrans API.

1. You ask your AI agent to integrate Midtrans into your app.
2. The agent calls MCP tools to retrieve relevant documentation.
3. MCP server returns structured Midtrans documentation, code examples, and schemas.
4. The agent generates accurate integration code based on official docs.

Getting Started

Prerequisites

• Python 3.11+
• One of: uv (recommended), Docker, or pip

Installation

git clone https://github.com/your-org/mcp-midtrans.git
cd mcp-midtrans

Running with uvx

The fastest way — no install needed:

# Run directly from PyPI
uvx mcp-midtrans

Or install as a global tool:

uv tool install mcp-midtrans
mcp-midtrans

Running with Docker

# Build the image
docker build -t mcp-midtrans .

# Run with stdio transport
docker run -i --rm mcp-midtrans

Or with Docker Compose:

docker compose up --build

Running with pip

pip install mcp-midtrans
mcp-midtrans

---

Editor & Agent Setup

VS Code + GitHub Copilot

Create or update .vscode/mcp.json in your workspace root:

Using uvx (recommended):

{
  "servers": {
    "midtrans": {
      "type": "stdio",
      "command": "uvx",
      "args": ["mcp-midtrans"]
    }
  }
}

Using Docker:

{
  "servers": {
    "midtrans": {
      "type": "stdio",
      "command": "docker",
      "args": ["run", "-i", "--rm", "mcp-midtrans"]
    }
  }
}

How to use:

1. Open VS Code with the workspace containing .vscode/mcp.json.
2. Open Copilot Chat (Ctrl+Shift+I / Cmd+Shift+I).
3. Switch to Agent mode (not Chat or Edit mode).
4. The MCP tools appear automatically — ask about Midtrans and Copilot calls the tools.
5. Example prompts:
   • "Help me integrate GoPay payment in my Django app"
   • "Show me how to handle Midtrans webhooks in Express"
   • "What's the charge request format for BCA Virtual Account?"

Claude Code (CLI)

Add to your project's .mcp.json (project root) or ~/.claude/mcp.json (global):

Using uvx:

{
  "mcpServers": {
    "midtrans": {
      "command": "uvx",
      "args": ["mcp-midtrans"]
    }
  }
}

Using Docker:

{
  "mcpServers": {
    "midtrans": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "mcp-midtrans"]
    }
  }
}

How to use:

1. Start Claude Code: claude
2. The MCP server connects automatically on startup.
3. Verify with: /mcp — you should see midtrans listed with 10 tools.
4. Ask about Midtrans — Claude will use the tools automatically:
   • "Integrate Midtrans Snap checkout into my FastAPI app"
   • "Generate a BNI VA charge request with customer details"
   • "How do I verify Midtrans webhook signatures in Go?"

Claude Desktop

Edit the config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "midtrans": {
      "command": "uvx",
      "args": ["mcp-midtrans"]
    }
  }
}

Restart Claude Desktop after saving. The 🔧 icon should show the Midtrans tools.

Cursor

Create .cursor/mcp.json in your workspace root:

{
  "mcpServers": {
    "midtrans": {
      "command": "uvx",
      "args": ["mcp-midtrans"]
    }
  }
}

Open Cursor Settings → Features → MCP to verify the server is active.

Key Files

File	Purpose
server.py	FastMCP server initialization, 10 tool handlers, Pydantic input models, enums
knowledge_base.py	Complete embedded Midtrans docs — all API refs, 15 payment methods, 5 language examples, 14 JSON schemas
pyproject.toml	Project metadata, deps (mcp[cli]>=1.2.0, pydantic>=2.0.0), hatchling build, entry point

Local Development

# Clone and set up
git clone https://github.com/your-org/mcp-midtrans.git
cd mcp-midtrans

# Create virtual environment with uv
uv venv
source .venv/bin/activate

# Install in editable mode
uv pip install -e .

# Run the server
mcp-midtrans

# Test with MCP Inspector (interactive tool testing)
npx @modelcontextprotocol/inspector mcp-midtrans

MCP Inspector opens a web UI where you can:

• See all registered tools and their input schemas
• Send test requests with custom parameters
• View formatted responses in real-time

Adding New Tools

1. Define input model in server.py:

class GetMyNewGuideInput(BaseModel):
    model_config = ConfigDict(str_strip_whitespace=True, extra="forbid")
    topic: str = Field(..., description="The topic to look up")

2. Add documentation to knowledge_base.py:

MY_NEW_GUIDE = """
# My New Documentation Section
...
"""

3. Register the tool in server.py:

@mcp.tool(
    name="midtrans_get_my_new_guide",
    annotations={"readOnlyHint": True, "destructiveHint": False, "idempotentHint": True},
)
async def midtrans_get_my_new_guide(params: GetMyNewGuideInput) -> str:
    """Description of what this tool returns."""
    return MY_NEW_GUIDE

4. Import the new constant in the server's import block.

Adding Documentation Content

All documentation lives in knowledge_base.py as Python string constants and dicts:

Variable	Type	Content
MIDTRANS_OVERVIEW	str	Products, environments, auth intro
AUTHORIZATION_GUIDE	str	Auth setup with code examples
API_ENDPOINTS	str	Complete endpoint reference table
PAYMENT_METHOD_DETAILS	dict	15 payment method guides (key = method name)
JSON_OBJECT_SCHEMAS	dict	14 JSON schema references (key = object type)
IMPLEMENTATION_EXAMPLES	dict	5 language examples (keys: python, django, nodejs, go, php)
STATUS_CODES	dict	Status code tables (key = range like "2xx")

To add content, append to the relevant constant or add a new entry to the dict.

Testing

# Syntax check
python -m py_compile src/mcp_midtrans/server.py
python -m py_compile src/mcp_midtrans/knowledge_base.py

# Verify tools register correctly
python -c "
from mcp_midtrans.server import mcp
tools = [t.name for t in mcp._tool_manager._tools.values()]
print(f'{len(tools)} tools registered:')
for t in tools:
    print(f'  - {t}')
"

# Verify languages
python -c "
from mcp_midtrans.knowledge_base import IMPLEMENTATION_EXAMPLES
print('Languages:', list(IMPLEMENTATION_EXAMPLES.keys()))
"

# Interactive testing
npx @modelcontextprotocol/inspector mcp-midtrans

---

Production Deployment

Docker Production Build

# Build with tag
docker build -t mcp-midtrans:latest .

# Tag for registry
docker tag mcp-midtrans:latest ghcr.io/your-org/mcp-midtrans:latest

# Push to container registry
docker push ghcr.io/your-org/mcp-midtrans:latest

Then users configure their MCP clients with Docker:

{
  "mcpServers": {
    "midtrans": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "ghcr.io/your-org/mcp-midtrans:latest"]
    }
  }
}

Publishing to PyPI

# Build distribution
uv build

# Upload to PyPI
uv publish
# or: twine upload dist/*

After publishing, users can run directly without cloning:

uvx mcp-midtrans
