Installation

pip install respcode-mcp

Or install from source:

git clone https://github.com/RespCodeAI/respcode-mcp
cd respcode-mcp
pip install -e .

Setup

1. Get your API key at respcode.com/settings/api-keys

Environment Variables

Variable	Required	Description
RESPCODE_API_KEY	Yes	Your API key
RESPCODE_API_URL	No	Custom API URL (default: https://respcode.com)

Troubleshooting

"RESPCODE_API_KEY environment variable not set"

Make sure your claude_desktop_config.json has the env section with your API key.
