Compatible with every major AI agent and IDE
What is the Pusher Channels MCP Server?
Connect your Pusher Channels infrastructure to any AI agent to orchestrate real-time messaging and monitor your application's pub/sub health through natural language.
What you can do
- Event Broadcasting — Trigger single or batch events across multiple channels with custom JSON payloads to update your frontend instantly.
- Channel Monitoring — List all active channels, filter by prefix, and fetch specific metadata like subscription counts or user counts.
- Presence Management — Retrieve lists of user IDs currently subscribed to presence channels to understand real-time engagement.
- Session Control — Terminate all active WebSocket connections for a specific user ID to handle security incidents or forced logouts.
- State Inspection — Query the detailed state of any specific channel to debug message flow or connection metrics.
How it works
- Subscribe to this server
- Provide your Pusher App ID, Key, Secret, and Cluster
- Start broadcasting events and managing connections from Claude, Cursor, or any MCP client
No more jumping into the Pusher Debug Console to manually trigger test events or check if a channel is active. Your AI acts as a real-time infrastructure operator.
Who is this for?
- Full-stack Developers — trigger test events and verify webhook payloads directly from the code editor.
- DevOps Engineers — monitor channel activity and user counts without opening the Pusher dashboard.
- Support Teams — quickly identify if a user is connected to a presence channel or terminate problematic sessions.
Built-in capabilities (6)
Fetch information for a specific channel
Fetch users in a presence channel
Fetch multiple channels
Terminate all connections for a user
Trigger multiple events in a single batch
Max 10KB data payload. Trigger an event on one or more channels
Why Pydantic AI?
Pydantic AI validates every Pusher Channels tool response against typed schemas, catching data inconsistencies at build time. Connect 6 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Pusher Channels integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your Pusher Channels connection logic from agent behavior for testable, maintainable code
Pusher Channels in Pydantic AI
Pusher Channels and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Pusher Channels to Pydantic AI through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for Pusher Channels in Pydantic AI
The Pusher Channels MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 6 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Pydantic AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
Pusher Channels for Pydantic AI
Every tool call from Pydantic AI to the Pusher Channels MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I send the same event to multiple channels at once?
Yes. The trigger_event tool accepts an array of channel names (up to 100) to broadcast your message simultaneously across your infrastructure.
How do I check which users are currently online in a presence channel?
Use the list_channel_users tool with the specific channel name (must start with presence-). It will return a list of all active user IDs.
Is it possible to force a user to disconnect?
Yes. The terminate_user_connections tool allows you to close all active WebSocket connections for a specific user ID immediately.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Pusher Channels MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
