MCP Server Development

Custom MCP servers, built to spec.

We design and build custom Model Context Protocol (MCP) servers — the secure adapter that lets Claude, ChatGPT, or Cursor take real, permissioned actions in your business systems. Shipped as production code you own.

What is an MCP server — and do you need one?

An MCP server is a standardized adapter that exposes a controlled set of actions — 'read inventory', 'draft a purchase order', 'look up an invoice' — to an AI assistant, with permissions and an audit trail. You need one when you want AI to act in your systems, not just chat. We build them custom, so the safety lives in the engineering: scoped tools, tight permissions, full logging, and human-approval gates on anything sensitive.

What we build

A production MCP server, end to end.

01

Scoped tool design

We map exactly which actions the AI can take in your systems — and which it can't. You approve the surface before we build a line of it.

02

Permissions + auth layer

Every action is scoped and authenticated. The AI gets a narrow, audited door into your stack — never the keys to everything.

03

Audit logging + approval gates

Every call is logged. Sensitive operations — anything touching money or data — can require a human to approve before they run.

04

Cross-client by design

One MCP server works across Claude, ChatGPT, Cursor, and whatever speaks MCP next. No per-assistant rebuilds, no lock-in.

05

Deployed to your infrastructure

Real code on your own servers, version-controlled and documented. No black-box connector you can't audit or change.

06

Built on your existing APIs

The server sits on top of the systems you already run and translates them into the standard AI clients understand.

FAQ

Questions, answered.

What is an MCP server in plain terms?

A secure adapter that lets an AI assistant use one of your tools — your store, database, or accounting system — through a controlled set of actions, with permissions and an audit trail.

How is a custom MCP server safer than a connector?

The safety isn't in the protocol — it's in the engineering. A custom server exposes only the actions you allow, scopes permissions tightly, logs everything, and can require human approval on sensitive steps.

Which AI assistants will it work with?

Any client that speaks MCP — Claude, ChatGPT, Cursor, and future ones. You build the server once and it works across all of them.

How long does an MCP server take to build?

A focused server is typically a 1–3 week build, depending on how many actions it exposes and how much permission logic it needs. We scope it precisely on a free call first.

What does it cost?

Custom MCP servers typically run $3,000–$10,000 depending on the number of actions and safety requirements. You only pay on delivery.
