MCP's are great for adoption of your service outside of developer circles. Non Technical users can click a link, trigger an OAuth flow and authenticate. You can't do that with API. API still is better for developers using a AI via a CLI but MCP is easier adoption for web or desktop based clients.

yes, this is the proper use case.

We hooked up fly.io's sprites mcp to our company claude and now all employees can spin up dev envs and actually prototype, verify or reproduce something before coming to engineering; doing it directly from web or wherever and it's properly authed and sandboxed through their accounts

Earlier quoted context omitted.

> - this article doesn’t enable tool search for starters where tokens start at near zero for MCP too Is that why I have to constantly remind Claude and ChatGPT that they do have access to a Github plugin that can access my account, instead of trying and failing to use the gh cli?

"claude, stop shelling out to grep, your search tool uses ripgrep and it's faster."

"claude: my harness tells me to use python's pathlib"

I use the official Blender MCP to drive Blender from Claude. Mostly creating specialized Geometry Nodes and Python utility scripts. I have made a couple of add on plug ins with it.

And Claude, more or less by itself, came up wth a workflow to create asset library Geometry Nodes that we distribute over our internal network.

An example:

I told Claude to do research on the design and nomenclature for straight back chairs and create a geometry node group that exposes the main nomenclature as parameters and generates watertight geometry. Claude produced something useful on the first try and with a little back and forth we got something very nice. I then told it to do the same thing for basic tables and it came back with a detailed plan to have a standard workflow that stores text file documentation, in markdown format, INSIDE of Blender, along with utility scripts to generate the node groups.

MCPs are diminishing in value a bit, because AI Agents are getting smarter about using API/CLIs. For example, I use gh cli via Claude instead of their MCP, because I already had cli setup, so no need to use MCP. MCPs can potentially have great value if they cross multiple sources and combine results. For example at work we use an in-house MCP for log/metrics search across five different (legacy) systems. It finds cor…

The main benefit of MCP today over just giving an agent a CLI is of course that you can be a lot more certain about what the agent can or can't do. Yes, an agent with CLI access and access to making HTTPS calls is a lot more efficient for most tasks, but also a lot more unpredictable and with much higher blast radius if it starts misbehaving compared to one that only have access to exactly the tools and data sources…

In practice that’s a lot of the value MCPs are providing.

Technically it’d work just as well to have a thin API wrapper or cli tool the agent is allowed to access.

at Hedgy we built an MCP to give our agents read-only access to cross-system data + context about what it means [0]. daily it helps me debug customer flows and think through features and priority. the advantage of MCP is that the tool description names what data it has so the agents know to just use it if they want that kind of data. as new data is added, everyone’s tool description updates. with a REST api or cli I…

A regular LLM already has read-only access to data
