File contents

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

Clone and build the signal-mcp server:

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

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

Bibliography References

general: 734 citations in bib.duckdb

SDF Interleaving

This skill connects to Software Design for Flexibility (Hanson & Sussman, 2021):

Primary Chapter: 3. Variations on an Arithmetic Theme

Concepts: generic arithmetic, coercion, symbolic, numeric

GF(3) Balanced Triad

signal-messaging (+) + SDF.Ch3 (○) + [balancer] (−) = 0

Skill Trit: 1 (PLUS - generation)

Connection Pattern

Generic arithmetic crosses type boundaries. This skill handles heterogeneous data.

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.
