How to Connect Latenode to OpenClaw via MCP

OpenClaw gives you a personal AI assistant in WhatsApp, Telegram, or Discord—one that runs on your machine and can execute scripts, manage files, and use its built-in skills. Latenode gives you a visual workflow engine in the cloud with 1,000+ app integrations and 400+ AI models. Connect them via MCP (Model Context Protocol), and your OpenClaw assistant can call your Latenode workflows as tools—create leads, send Slack messages, update your CRM, or run any automation you’ve built in Latenode—without leaving the chat.

This guide walks you through how to connect Latenode to OpenClaw via MCP using the Latenode MCP documentation: first you expose Latenode scenarios as MCP tools, then you add the Latenode MCP server to OpenClaw so your agent can discover and call those tools.

Key takeaways:

• MCP is a standard that lets AI systems (like OpenClaw) call external tools. Latenode’s MCP Trigger turns your scenarios into an MCP server; each branch becomes a tool with a name, description, and parameters.
• In Latenode: create a scenario → add MCP Trigger → connect nodes (e.g. Code, HTTP, integrations) → set Tool Name and Tool Description → define input parameters (fromMCP) → save and copy the Server URL.
• In OpenClaw: add a new MCP server and paste the Latenode Server URL. If your MCP Trigger uses authentication, provide the API key in OpenClaw. Your agent will then see and call your Latenode tools from chat.
• Use MCP Response in Latenode to return only the data the AI needs; follow best practices for tool names, descriptions, and parameters so OpenClaw uses your tools correctly.

Why connect Latenode to OpenClaw via MCP?

• One assistant, many apps. OpenClaw stays your single interface in messaging apps; Latenode adds 1,000+ apps (CRM, support, payments, databases, etc.) as tools the agent can invoke.
• No duplicate logic. Build and maintain automations once in Latenode (visual builder, error handling, retries); OpenClaw just calls them when the user asks.
• Standard protocol. MCP is a common way for AI clients to talk to external tools. Latenode exposes your workflows as MCP tools; OpenClaw (as an MCP-compatible client) discovers and calls them.

What you need before you start

• A Latenode account (sign up free).
• OpenClaw installed and running (see What is OpenClaw? or openclaw.ai).
• At least one Latenode scenario with an MCP Trigger configured (we’ll build this below).

Part 1: Expose your Latenode workflows as MCP tools

Everything in this section is based on MCP Nodes in the Latenode docs.

Step 1: Create a scenario and add MCP Trigger

1. In Latenode, create a new scenario (or open an existing one).
2. Add the MCP Trigger node. This node turns the scenario into an MCP server. Every node connected directly to the MCP Trigger becomes a separate tool that OpenClaw (and other MCP clients) can discover and call.

Step 2: Configure the MCP server (optional but useful)

In the MCP Trigger node settings:

Step 3: Define each tool (name, description, parameters)

For each node connected directly to the MCP Trigger, that node is one tool. Configure it in that node’s settings:

Step 4: Add input parameters (what the AI sends when it calls the tool)

Parameters are the inputs your tool expects. Define them in the first node of each tool branch:

Example for a “create lead” tool:

The AI will pass these when it invokes the tool; your scenario can use them in later nodes (e.g. HTTP request to CRM, Slack node).

Step 5: Build the rest of the tool logic

After the first node (where you set Tool Name, Description, and parameters), add any nodes you need: HTTP, Slack, Code, AI Agent, Database, or any of Latenode’s 1,000+ integrations. The tool runs this chain when OpenClaw calls it. You can use conditions, loops, and error handling as usual.

Step 6: Control what the AI sees (MCP Response)

By default, the last node’s output is sent back to the AI (e.g. full HTTP response with headers). To keep responses clean and relevant:

• Add an MCP Response node at the end of the tool branch.
• In it, map only the fields you want (e.g. body, or { "leadId": "...", "status": "created" }) from previous nodes.

That way OpenClaw gets a short, structured answer instead of raw API payloads.

Step 7: Save and copy the Server URL

1. Save the scenario.
2. In the MCP Trigger node, copy the Server URL.
3. You’ll use this URL in OpenClaw in Part 2.

Multiple tools in one scenario

You can expose many tools from a single scenario. Connect multiple branches to the MCP Trigger—each branch is one tool with its own Tool Name and Tool Description. Latenode creates an automatic route filter so each request is routed to the correct branch. For details and a diagram, see Multiple tools in the docs.

Part 2: Connect OpenClaw to your Latenode MCP server

Latenode exposes your tools over HTTP/SSE (Server-Sent Events). OpenClaw can connect to remote MCP servers when configured with the server’s URL.

1. Open your OpenClaw configuration (agent settings or config file where MCP servers are defined).
2. Add a new MCP server and set:
   • URL / Server URL: paste the Server URL you copied from the Latenode MCP Trigger.
   • Name (if applicable): e.g. latenode or Latenode workflows.
3. If you enabled Authentication on the MCP Trigger in Latenode, provide the API key in OpenClaw’s MCP server configuration (header or auth field, depending on your OpenClaw version).
4. Save and restart or reload OpenClaw so it discovers the new server.
5. Verify that your Latenode tools appear in OpenClaw’s tool list (or in the agent’s available tools). You can then ask your OpenClaw assistant (e.g. in Telegram or Discord) to perform an action that maps to one of your tools (e.g. “Create a lead for John, [email protected]”) and confirm it calls the Latenode scenario.

OpenClaw’s MCP client support may differ by version (e.g. stdio vs HTTP, or use of a bridge like mcp-remote for HTTP URLs). For the exact steps and fields in your build, check the OpenClaw documentation or OpenClaw GitHub for “MCP” or “add MCP server.” The principle is always the same: add the Latenode Server URL as the MCP server endpoint so OpenClaw can call your Latenode tools.

For other MCP clients (Cursor, Claude Desktop, etc.), the same Server URL is used; see Connecting to MCP Tools in the Latenode docs.

Example: Simple “echo” tool (from Latenode docs)

To test the pipeline end-to-end, you can start with the minimal example from the Latenode MCP docs:

1. Create a new scenario → add MCP Trigger → set Server Description (e.g. Test MCP server).
2. Connect a Code node to the MCP Trigger.
3. In that Code node, set:
   • Tool Name: echo
   • Tool Description: Returns the provided text. Use for testing.
   • Parameter: Key message, Type fromMCP, Description Text to return.
4. In the Code node body, return the message:

return { result: msg.message };

5.Save the scenario, copy the Server URL from the MCP Trigger, and add it in OpenClaw as an MCP server. Then ask OpenClaw to “echo hello” (or similar) and confirm it calls the tool and you get { result: "hello" } (or the text you sent).

Once this works, replace the Code node with real logic (e.g. HTTP to your CRM, Slack node) and add more branches for more tools.

Best practices (from Latenode docs)

• Tool descriptions: Write so the AI knows when to use the tool. Good: “Creates a task in Asana. Accepts task title and optional deadline. Returns created task ID and link.” Bad: “Creates task.”
• Parameters: Use clear names (user_email not param1), specify format in the description (e.g. “Date in YYYY-MM-DD format”), and mark optional parameters.
• Response data: Use MCP Response to return only what the AI needs; avoid exposing full HTTP bodies or internal IDs unless useful. Structure the response for readability.

See Best practices and Limitations in the Latenode MCP docs for more.

Troubleshooting

• Tools don’t appear in OpenClaw:
• Ensure Tool Name is set on every node connected to the MCP Trigger. Confirm you’re using the correct Server URL from the MCP Trigger and that the scenario is saved. If Authentication is on, make sure OpenClaw is sending the API key.
• Connection drops or timeouts:
• MCP uses SSE; the connection must stay stable. Keep tool runs reasonably fast and return only necessary data (use MCP Response). See Limitations: tool execution is limited by the scenario timeout.
• Authentication errors (401/403):
• If the MCP Trigger has Authentication enabled, regenerate or copy the API key in Latenode and set it in OpenClaw’s MCP server config. Confirm Authentication is enabled/disabled as intended in the MCP Trigger.

Summary

1. In Latenode: Create a scenario → add MCP Trigger → connect one or more branches → for each branch set Tool Name, Tool Description, and fromMCP parameters → add MCP Response if you want clean responses → save and copy the Server URL.
2. In OpenClaw: Add an MCP server with the Latenode Server URL (and API key if you use Authentication). Reload OpenClaw so it discovers your tools.
3. Use your OpenClaw assistant in chat to trigger actions that map to your Latenode tools; your assistant now has access to 1,000+ apps through Latenode.
