RELAY // WebMCP asymmetric co-op

You see the bomb. The agent sees the manual.

Neither side has enough information to win alone. The human gets a visual puzzle state rendered outside the agent tool surface. The agent gets narrow WebMCP tools: read manual pages, inspect one agent-only signal, and propose actions. Talk or lose.

Human station

Visual bomb surface

Describe what you see to the agent. Puzzle values are painted to canvas and are not returned by any WebMCP tool.

A · Wire matrixunsolved

Waiting for the agent to propose a wire.

B · Glyph keypadunsolved

Waiting for the agent to propose a press order.

C · Switchboardunsolved

Waiting for the agent to propose a switch.

D · Reverse linkunsolved

Roles reverse here. The agent can inspect a classified token sequence that you cannot see. You have the decoder table the agent cannot read through WebMCP. Ask the agent for the sequence, decode it, then transmit the 4-digit result.

How to play

The conversation is the controller

1 · Human observesTell the agent colors, symbols, switches, serial details, or anything else visible on your bomb.

2 · Agent interpretsThe agent reads the hidden manual through WebMCP and submits a proposal tool call.

3 · Human commitsThe proposal appears here. You decide whether to trust it. Wrong actions create strikes and time penalties.

Agent station

WebMCP capability surface

These are the only game-specific facts intentionally exposed to the agent.

Asymmetry boundary: no tool returns wire colors, glyphs, switch positions, serial data, or the human decoder table. The reverse signal is intentionally agent-only.

Shared telemetry

Radio traffic

Tool calls and staged proposals appear here, but manual text does not leak to the human station.

Give the agent this mission

“We are playing RELAY. Use this page's WebMCP tools as your only source of game information. Read the briefing/manual as needed. Ask me what I see, reason from my descriptions, and submit proposals with the provided tools. Do not guess. For the Reverse Link, inspect the agent-only signal and tell me the tokens in order.”
