Both convert REST APIs into MCP tools. Invok is an open-source, self-hosted proxy that reads OpenAPI specs. DataFaucet captures traffic from any web app and deploys a managed endpoint. Different trade-offs for different situations.

No OpenAPI spec? No problem.
DataFaucet captures APIs from any web app, including ones with no documentation.
Invok is a self-hosted proxy that sits between your MCP client and any REST API. You provide an OpenAPI spec (or write a JSON recipe), and Invok dynamically registers those endpoints as MCP tools. Credentials are encrypted locally and never reach the LLM. You get full control and data sovereignty.
DataFaucet works from the other direction. Instead of starting with a spec file, you browse the target web app and DataFaucet captures the underlying API calls. No spec needed, no Docker setup, no configuration files. The output is a managed MCP server endpoint that any client connects to immediately.
The fundamental trade-off: Invok gives you full self-hosted control but requires technical setup and an existing API spec. DataFaucet trades self-hosting for speed and accessibility, working even when no spec exists.
They create demand. We create supply.
