Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade E, and why

channels-setup scanned grade E with 4 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Downloads and executes remote codehighSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

curl -s -X POST http://localhost:21568/auth/local | python3 -c "import sys,json; print(json.load(sys.stdin).get('token',''))"

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

cat ~/.claude/plugins/marketplaces/gettalon-talon-plugins/plugins/talon/.mcp.json 2>/dev/null || echo "Not found"

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

cat ~/.claude/plugins/marketplaces/gettalon-talon-plugins/plugins/talon/.mcp.json 2>/dev/null || echo "Not found"

Channels Setup Guide

Help the user set up the Talon Channels universal server so any client can connect to Claude Code via WebSocket or platform adapters (Telegram, Discord, Slack, etc.).

Development Mode

During the research preview, channels require an allowlist. To use talon-channels:

claude --dangerously-load-development-channels plugin:channels@gettalon-talon-plugins

The plugin: prefix tells Claude Code to load this channel plugin and bypass the allowlist check.

Channel Types

Type Env Var Required Credentials
WebSocket (default) websocket None (local only)
Telegram telegram TELEGRAM_BOT_TOKEN
Discord discord DISCORD_BOT_TOKEN
Slack slack SLACK_BOT_TOKEN, SLACK_APP_TOKEN
iMessage imessage None (macOS only)

Steps

1. Check Current Configuration

# Check what channel is configured
cat ~/.claude/plugins/marketplaces/gettalon-talon-plugins/plugins/talon/.mcp.json 2>/dev/null || echo "Not found"

2. Configure Channel Type

Set TALON_CHANNEL env var in the plugin's .mcp.json:

WebSocket (default):

{
  "channels": {
    "command": "npx",
    "args": ["-y", "-p", "@gettalon/channels-sdk", "channels"]
  }
}

Telegram:

{
  "channels": {
    "command": "npx",
    "args": ["-y", "-p", "@gettalon/channels-sdk", "channels"],
    "env": {
      "TALON_CHANNEL": "telegram",
      "TELEGRAM_BOT_TOKEN": "your-bot-token"
    }
  }
}

3. Check Server Health (WebSocket mode)

curl -s http://localhost:21568/health 2>/dev/null || echo "Server not running"

3. Get Auth Token

Clients need a token to connect:

curl -s -X POST http://localhost:21568/auth/local | python3 -c "import sys,json; print(json.load(sys.stdin).get('token',''))"

Or read from discovery file:

cat ~/.talon/channels_token 2>/dev/null || echo "No token file"
