When & Why to Use This Skill

This Claude skill enables seamless integration with Signal Messenger via the Model Context Protocol (MCP). It empowers AI agents to securely send and receive encrypted messages, manage conversations, and automate complex communication workflows, bridging the gap between LLM intelligence and private, secure messaging platforms.

Use Cases

  • Automated Notifications: Configure your AI agent to send real-time system alerts, deployment status updates, or critical incident reports directly to Signal contacts or groups.
  • Conversation Summarization: Efficiently catch up on missed discussions by having Claude read incoming Signal messages and provide concise summaries of key action items and decisions.
  • Secure Customer Support: Deploy an automated assistant capable of handling sensitive customer inquiries over Signal's end-to-end encrypted channel for enhanced privacy.
  • Workflow Triggering: Use incoming Signal messages as triggers for complex automated workflows, such as updating project boards or executing scripts based on specific text commands.

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

Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

Scientific Computing

  • scipy [○] via bicomodule
    • Hub for numerical/scientific computation

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.
