Introduction
Needle is an outbound engine for revenue teams. Keep a list of leads, add connected accounts for LinkedIn and Instagram, and enroll people in campaigns. The same work is available in the dashboard, over the REST API, and as MCP tools.

REST API
The public API lives under /api/v1. See the API Reference for endpoints, parameters, and schemas.
MCP
Connect an agent at /mcp/v1 with the same API key. Listing tools does not require a key; calling them does. See the MCP catalog for every tool.
OpenAPI
The machine-readable spec is at /api/v1/openapi. Use it to generate clients or import the API into your own tooling.
For agents
Start with the onboarding skill. It routes to MCP, the REST API, credentials, and common outbound workflows.
