What stands out most to me is how Fastn removes the integration work that usually eats the front end of any agent project. Reaching the tools an agent needs used to mean building and maintaining a connection for each one. With Fastn those connectors are already available through a single MCP endpoint, so I start from "what should this agent do" instead of "how do I get it talking to anything."
The connector and workflow tooling is what I touch most often. I can build a connector against a live API, test it, and wire it into a workflow without leaving the platform, which keeps the whole build in one place. The OAuth handling deserves a specific mention, since auth is usually where these projects get stuck and here it mostly just works. Review collected by and hosted on G2.com.
Error messages on failed connections could be clearer a few times I wasn't sure if the issue was my setup or the connector itself, which cost some debugging time. Review collected by and hosted on G2.com.
