This guide shows how to connect n8n to Alchemyst’s REST API, so every automation you build can read and write context.

​
Prerequisites

  • An n8n account (cloud or self-hosted)
  • An Alchemyst API key from the dashboard
  • Basic familiarity with n8n’s node editor

​
Connect n8n to Alchemyst

​
Setting Up the HTTP Request Node

  1. Add an HTTP Request node anywhere in your workflow.
  2. Under Authentication, pick Generic Credential Type → Bearer Token.
  3. Create a credential, paste your Alchemyst API key, and save it.
  4. Set Method to POST and Content Type to JSON.
  5. Use one of these endpoints:
    • Add context: https://platform-backend.getalchemystai.com/api/v1/context/add
    • Search context: https://platform-backend.getalchemystai.com/api/v1/context/search
Re-use the same HTTP Request node as a template by duplicating it inside other workflows.

​
Setting Up the MCP Node

  1. Add an MCP node in your workflow by pasting the below code snippet.
{
  "name": "Alchemyst MCP Client",
  "nodes": [
    {
      "id": "alchemyst-mcp-client-1",
      "name": "Alchemyst MCP Client",
      "type": "@n8n/n8n-nodes-langchain.mcpClientTool",
      "typeVersion": 1.2,
      "position": [300, 300],
      "parameters": {
        "endpointUrl": "https://mcp.getalchemystai.com/mcp/sse",
        "serverTransport": "sse",
        "authentication": "bearerAuth",
        "include": "selected",
        "includeTools": [
          "alchemyst_ai_context_mcp_search_context"
        ],
        "options": {
          "timeout": 60000
        }
      },
      "credentials": {
        "httpBearerAuth": {
          "id": "",
          "name": ""
        }
      }
    }
  ],
  "connections": {}
}
  1. Open the node you just added and confirm the following settings:
    • Endpoint: https://mcp.getalchemystai.com/mcp/sse
    • Authentication: Bearer Auth
  2. Create a Bearer Auth credential:
    • Click Create New Credential
    • Paste your Alchemyst API key into the Bearer Token field
    • Save the credential and select it for the MCP node
Once these steps are complete, the MCP node can call Alchemyst tools inside your workflows.
