What is the Hookdeck MCP Server?
Connect your Hookdeck account to any AI agent to orchestrate your webhook infrastructure through natural conversation. Hookdeck provides the reliability layer for your event-driven architecture, and this server puts that power in your chat interface.
What you can do
- Connection Management — List, create, and update connections that route webhooks from sources to destinations.
- Traffic Control — Instantly pause or resume event routing for specific connections to manage maintenance windows or outages.
- Source Monitoring — Retrieve and count your webhook sources to understand where your incoming data originates.
- Lifecycle Operations — Enable or disable connections and manage their rules via JSON payloads without leaving your workflow.
- Deep Inspection — Fetch specific metadata for any connection or source using unique IDs to debug routing issues.
How it works
- Subscribe to this server
- Enter your Hookdeck API Key
- Start managing your webhook reliability layer from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Backend Engineers — quickly toggle webhook traffic or check connection statuses during deployments.
- DevOps Teams — monitor the health of event-driven pipelines and manage sources programmatically.
- Integration Specialists — verify routing rules and connection counts across different environments.

Every tool call from LangChain to the Hookdeck MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How can I temporarily stop webhooks from being delivered to a destination?
You can use the pause_connection tool with the specific Connection ID. This will halt event routing until you call unpause_connection.
Can I see how many active sources I have configured?
Yes, use the count_sources tool to get the total number of sources, or list_sources to see the details of each one.
Is it possible to update connection rules through the AI?
Absolutely. Use the update_connection tool by providing the Connection ID and a JSON body containing the new configuration rules.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
