cd missive-mcp-server
npm install
npm run build

Set your Missive API token:

export MISSIVE_API_TOKEN="your-missive-api-token-here"

Run the HTTP server:

npm run http
# Or for production: npm run http:prod

In N8N MCP Client node:
- SSE Endpoint: http://localhost:3000/sse
- Authentication: Bearer Auth
