Installation
# get the repository
git clone https://github.com/exekerey/3xpl-mcp.git
cd 3xpl-mcp
# create and activate virtual environment
uv venv
source .venv/bin/activate
# install dependencies
uv pip install -e .
MCP configuration:
{
"mcpServers": {
"3xpl_API": {
"command": "/Users/danial/.local/bin/uv",
"args": [
"run",
"--with",
"mcp[cli]",
"mcp",
"run",
"/Users/danial/3xpl_mcp/main.py"
],
"env": {
"THREEXPL_API_KEY": ""
}
}
}
}
*Note: Set your API key from 3xpl to use the main API.
If the THREEXPL_API_KEY field in the config file is left blank,
the MCP server will use the sandbox API, which has rate limits.
*Note 2: if MCP server doesn't start you might need to provide full path to uv in the command field.
