Service	What an agent can do	Auth	MCP server	Free tier	Details (with sources)	Notes	Proof (ratings, usage)
Activepieces	Build, run and manage no-code flows across 400+ apps via REST API or the built-in MCP server.	API key `Authorization: Bearer <api_key>`	official	free: open-source, self-hostable at no cost; cloud free plan gives 100 credits/day, no card required	Base URL: https://cloud.activepieces.com/api/v1 Free plan: 100 credits per day, unlimited flows; free plan lists MCPs and API access, no card ↗ Example call: list flows in a project: GET https://cloud.activepieces.com/api/v1/flows?projectId={projectId}&status=ENABLED ↗ Unit price: 1 credit per flow run (AI steps 2-20 credits); Plus $20/mo includes 10,000 credits, overage $0.007/credit ↗	MCP server URL is per-instance (https://your-instance.com/mcp); OAuth-based client auth, and connection secrets/API keys are never exposed through MCP tools.
