  "description": "A charting bench whose capabilities are MCP tools. This origin serves no MCP endpoint: the server runs in the page at /layout/?pilot=1, and over HTTP it runs on the TapeBench companion on your own machine ({companion-origin}/mcp?token={token}). Tools, resources and prompts are not listed here — ask the server, once you are connected to one.",

        "argsNote": "Your tool arguments go in `args`, as the second step shows. `arguments` — MCP's own name for that field — is accepted here as an alias for it. Send them under any other name and the call is refused, naming the name you used; send no arguments at all, as the first step does, and the tool's own schema decides whether that is a complete call.",

Both placeholders come from that line; neither has a default worth guessing. TapeBench publishes no address to obtain the companion yet: if you are not already running one, these snippets are a shape to keep, and the door that works today is the pilot above — it needs a browser and nothing else.",
