Why MCP, and Why It’s Tricky

An MCP server is API design under adversarial conditions: the caller is a model. These are the gaps between a demo server and one you can hand to customers:
Call Icon

Challenge

AI agents can't see your product at all.

Solution

An MCP server exposes your capabilities as tools assistants can call — making you present wherever your customers' agents do their work.
Call Icon

Challenge

Models misuse vague tools, confidently.

Solution

We design tool names, descriptions and schemas the way models actually read them — the difference between correct calls and confident chaos.
Call Icon

Challenge

Auth must be user-delegated, not one big API key.

Solution

OAuth flows and per-token scoping so an assistant can only ever do what its human could do.
Call Icon

Challenge

A confused agent can hammer your API.

Solution

Rate limits, bounded queries and response shaping keep costs and blast radius contained.
Call Icon

Challenge

The standard is young and still moving.

Solution

We build the thin-layer way: your logic stays in your API, and the MCP surface stays cheap to update as the spec evolves.

"The service that Fuselio has offered us has been amazing.

After some years of trying to develop an app for our medical diagnostics company in Mexico they were able to help us bring the app to life. Their service has been great.

Our time zone differences has been a challenge but they where very flexible with us and the communication channels used where very efficient. The best thing about the service was the response time, the disposition and the help when developing the APIs."

FAQ

FAQs on MCP Server Development

What is an MCP server, in one sentence?

A standardised interface that lets AI assistants like Claude and ChatGPT securely use your product's features as tools, with your user's permission.

Do we need one if we already have an API?

Your API is 80% of the prerequisite. The MCP server is a thin, model-friendly layer over it — what's left is tool design, auth delegation and packaging, which is exactly what we build.

Which assistants support MCP?

Claude natively, plus the major agent frameworks, with adoption spreading across platforms through 2025–26. It's an open standard, not a single-vendor bet.

Remote server or local package?

Remote for SaaS products your customers connect from their assistant's settings; local packages for developer tools. We build and document both.

How do users connect it?

Remote: they add your server URL in their assistant's connector settings and authorise via OAuth. Local: an install command. We ship the docs for both.

Can agents break things in our product?

Only what you expose — scoping is the core of the design. Read-only tools first, writes behind confirmation, destructive actions never.

What does it cost to run?

MCP servers are thin: typical hosting is a small edge deployment measured in dollars, not hundreds, per month. The build is the investment; the run-rate is noise.

Is MCP going to stick around?

It's an open standard with thousands of servers in the wild in 2026. Like any young standard it will evolve — which is why the thin-layer build keeps your update cost low.
