What is the Fusion MCP Server?

Local Fusion MCP: panel->judge->synthesis on the Claude CLI subscription, no OpenRouter.

The short version

Local Fusion MCP server — replicates the OpenRouter Fusion mechanism on your local Claude CLI subscription. No OpenRouter, no separate token bill, one wallet.

What it needs from you

Needs the Claude CLI (claude) on PATH and an active Claude Pro/Max subscription — the server fans out local claude -p calls. Without it the tool will not run.

More MCP options
