Signal Messaging via MCP

Interact with Signal messenger through the local MCP server.

Setup

The Signal MCP server is configured in ~/.mcp.json:

{
  "signal": {
    "command": "cargo",
    "args": ["run", "--release", "--example", "signal-server-stdio"],
    "cwd": "/Users/alice/signal-mcp",
    "env": {
      "RUST_LOG": "signal_mcp=info"
    }
  }
}

Prerequisites

1. Clone and build the signal-mcp server:

   cd /Users/alice/signal-mcp
   cargo build --release --example signal-server-stdio
   

2. Register/link your Signal account with the server

Usage

Use read_mcp_resource to interact with Signal:

{"server": "signal", "uri": "signal://..."}

Capabilities

• Send messages to contacts or groups
• Read incoming messages
• List conversations
• Handle attachments

Troubleshooting

• Ensure the server starts: cargo run --release --example signal-server-stdio
• Check logs: RUST_LOG=signal_mcp=debug
• Verify Signal account is registered/linked
• Restart Amp after config changes

Cat# Integration

This skill maps to Cat# = Comod(P) as a bicomodule in the equipment structure:

Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826

GF(3) Naturality

The skill participates in triads satisfying:

(-1) + (0) + (+1) ≡ 0 (mod 3)

This ensures compositional coherence in the Cat# equipment structure.
