Compatible with every major AI agent and IDE
What is the Ably MCP Server?
Connect your Ably account to any AI agent to orchestrate real-time communication infrastructure through natural language. This server provides full access to the Ably REST API for robust pub/sub messaging and presence management.
What you can do
- Messaging — Publish messages to single or multiple channels, retrieve message history, and update or delete existing messages.
- Presence Tracking — Monitor real-time member status and history within specific channels to see who is online.
- Push Notifications — Send direct push notifications to devices or client IDs for mobile and web engagement.
- Channel Management — List active channels, fetch metadata, and monitor usage statistics across your application.
- Security & Tokens — Revoke tokens before expiry to maintain tight control over your real-time infrastructure access.
How it works
- Subscribe to this server
- Enter your Ably API Key
- Start managing your real-time streams from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Backend Developers — Debug real-time message flows and check channel states directly from the terminal or IDE.
- DevOps Engineers — Monitor application stats and manage API key security without leaving the command line.
- Product Engineers — Test push notification payloads and presence logic during feature development.

Ably in OpenAI Agents SDK
Ably and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Ably to OpenAI Agents SDK 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 Ably in OpenAI Agents SDK
The Ably 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 14 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK 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.

How Vinkius secures
Ably for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Ably MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I see who is currently active in a specific channel?
Yes. Use the get_presence tool with the target Channel ID to retrieve a list of all members currently connected and their status.
How do I send a single message to multiple channels at once?
You can use the batch_publish tool. Provide a comma-separated list of channel IDs and the data payload to broadcast to all of them in one request.
Is it possible to retrieve the history of messages sent to a channel?
Absolutely. Use the get_messages tool to fetch the message history for any channel, with options to filter by timestamp or limit the number of results.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
