MCP server development

It's a small service that sits between an AI app and your systems. Claude or ChatGPT connects, sees a list of tools you've described (say, look up an order, or open a ticket) and calls them when someone asks. MCP, the Model Context Protocol, is an open standard Anthropic published in November 2024. OpenAI and Google adopted it in 2025.

Mostly in who reads it. A developer reads your API docs once and then writes code. A model reads the tool descriptions every time, and decides from those alone whether to call anything, so the wording matters more than you'd expect. The MCP server nearly always sits in front of an existing API rather than replacing it.

Use OAuth, so each person signs in and the agent can only do what they could. Validate inputs, rate-limit, and log every call along with its arguments (you'll want that log the first time someone asks why it did something). We also ship read-only tools first and add writes later, once you've seen how it behaves.

About five weeks on our standard plan. Week one is requirements and architecture. Weeks two and three build the core server, week four is integration and testing, and in week five it goes to production with docs.
