Quick Start
Two install modes — pick whichever your MCP client supports.
Option A — Remote (Streamable HTTP, zero install)
For clients with native remote MCP support (Claude Desktop ≥ 0.8, Cursor, Windsurf, VS Code MCP, etc.)
{
"mcpServers": {
"macalc": {
"url": "https://macalculatriceenligne.com/api/mcp"
}
}
}Option B — Local stdio proxy (works everywhere)
For clients that only speak stdio, or sandboxed environments:
{
"mcpServers": {
"macalc": {
"command": "npx",
"args": ["-y", "macalc-mcp"]
}
}
}Or with Docker:
{
"mcpServers": {
"macalc": {
"command": "docker",
"args": ["run", "-i", "--rm", "ghcr.io/tresor4k/macalc-mcp:latest"]
}
}
}
