Building agents with Mastra?
DataFaucet generates servers your Mastra agents connect to via MCP client toolset.
Mastra gives you the agent runtime: orchestration, memory, RAG pipelines, and workflow execution. Its MCP client support means agents can discover and call tools from any MCP server automatically.
DataFaucet operates at the tool generation layer. It captures API traffic from any web app and generates hosted MCP servers. Since Mastra supports MCP natively, you can wire DataFaucet servers directly into Mastra agents without writing tool definitions.
Use them together: DataFaucet for instant tool generation from any app, Mastra for the TypeScript agent that orchestrates those tools with memory and RAG.
They create demand. We create supply.
