What is frontmcp-channels?

A guide for building FrontMCP channels that push live events into Claude Code or another compatible MCP client. Events can come from webhooks, errors, completed jobs, service connections, file changes, or chat messages.

Use it for CI failure alerts, monitoring notifications, deployment updates, job-completion messages, file watchers, or chat bridges such as Slack, Telegram, WhatsApp, and Discord.

It explains when the server should send information automatically instead of waiting for the client to ask for it. This helps connect external events and two-way conversations to an AI coding session.

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.

Model	Per session	Once invoked
Fable 5	$0.00140	$0.02250
Opus 5	$0.00070	$0.01125
Sonnet 5	$0.00028	$0.00450
Haiku 4.5	$0.00014	$0.00225

Security

Grade A, and why

frontmcp-channels scanned grade A with 0 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

FrontMCP Channels

Build push-based notification channels that stream real-time events into Claude Code. Channels let your MCP server forward webhooks, application errors, agent completions, job results, and chat messages directly into Claude's context, with optional two-way reply support.

When to Use This Skill

Must Use

You need Claude Code to react to external events (CI failures, monitoring alerts, deploy status)
You are building a chat bridge (WhatsApp, Telegram, Slack, Discord) for Claude Code
You want agents or background jobs to notify Claude Code upon completion

Skip When

You only need standard MCP resource subscriptions (use @Resource with resources/subscribe)
Your client is not Claude Code and does not support experimental['claude/channel']
You need request-response patterns (use @Tool instead)

Decision: Use channels when you need server-initiated push notifications into Claude Code. Use resources when the client pulls data on demand.

Prerequisites

@frontmcp/sdk >= 1.0.0
Basic understanding of @FrontMcp, @App, and @Tool decorators
For webhook sources: HTTP transport (not stdio-only)
For chat bridges: external API credentials (WhatsApp Business API, Telegram Bot Token, etc.)

Steps

Choose your channel source type from the Scenario Routing Table
Create a channel class or function
Register it in your app
Enable channels in @FrontMcp config
Test with Claude Code using --dangerously-load-development-channels

Scenario Routing Table

Scenario	Reference	Description
Webhook alerts (CI, monitoring)	`references/channel-sources.md`	Forward HTTP webhooks into Claude
Application error forwarding	`references/channel-sources.md`	Push app errors via event bus
Agent completion notifications	`references/channel-sources.md`	Notify when agents finish
Job/workflow completion	`references/channel-sources.md`	Notify when jobs complete
Service connector (WhatsApp, etc.)	`references/channel-sources.md`	Persistent connection with bidirectional tools
File/log watcher	`references/channel-sources.md`	File system change monitoring
Event replay for offline sessions	`references/channel-sources.md`	Buffer events for later delivery
WhatsApp/Telegram chat bridge	`references/channel-two-way.md`	Two-way messaging with Claude
Slack/Discord integration	`references/channel-two-way.md`	Chat platform bridges
Permission relay	`references/channel-two-way.md`	Remote tool approval via chat

What ships with it

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
