"Fastn’s Agentic platform Makes Agent Tooling and Embedding Effortless"

5/5

What do you like best about Fastn?

What I value most about Fastn is how it collapses the gap between an AI agent and the tools it actually needs to act on. The MCP gateway lets me expose a whole set of connectors—Notion, Slack, Gmail, and others—through a single endpoint, so instead of wiring up bespoke integrations for every agent I build, I point it at Fastn and the tools are just there. That's saved me hours on every agentic project.

The connector and workflow layer is the standout for me. Being able to build, probe, and publish a custom connector against a real API, then orchestrate it in a workflow without leaving the platform, means I can go from idea to working demo in a single session. The OAuth handling in particular removes a chunk of auth plumbing that usually eats the most time. Review collected by and hosted on G2.com.

What do you dislike about Fastn?

Nothing in particular, I think so far its working fine for me Review collected by and hosted on G2.com.

What problems is Fastn solving and how is that benefiting you?

Here's the same answer with the em dashes removed:

Before Fastn, connecting an AI agent to the tools it needed meant building and maintaining a separate integration for each service like Notion, Slack, Gmail, and internal APIs, and handling auth for every one individually. That setup work was the slowest part of every agentic project, and it didn't scale. Each new tool meant more bespoke plumbing to write and keep alive.

With Fastn's MCP gateway, those connectors sit behind a single endpoint, so an agent gets access to the whole toolset without per-integration wiring. The practical result is that I now go from "idea" to a working multi-tool agent demo in a single session instead of spreading it across days. For the agentic systems I build and demo, that has cut integration setup time dramatically and let me stand up live, end-to-end agent demos that previously would have taken a week of glue code.

"Good integration platform for SaaS companies"

4/5

What do you like best about Fastn?

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.

What do you dislike about Fastn?

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.

What problems is Fastn solving and how is that benefiting you?

Fastn solves the integration problem at the heart of building AI agents. An agent is only useful if it can reach the tools it needs, and that used to mean building and maintaining a separate connection for each service, each with its own auth. That overhead was the slowest part of every project and scaled badly as the number of tools grew. Review collected by and hosted on G2.com.
