# Build MCP servers, tools, skills and agent harnesses

We build MCP servers, tools and skills around your systems and sources, and set up agent harnesses so every AI assistant your teams use follows the same rules.

## Your systems, in the AI your teams use

We build the connections your AI is missing: MCP servers for your systems and approved sources, narrow tools that return answers with their source and date, and skills that string them together for a whole job. Then we set up the harness around them, so every assistant follows the same rules.

## What we build with you

- **MCP servers**: Connect your systems, data and approved sources to Claude, ChatGPT, Copilot and other clients, with sign-in and scoped access.
- **Tools**: Narrow checks and calculations that return the answer with its source and date.
- **Skills**: Guided workflows that string tools together for a whole job, with the points where a person reviews.
- **Agent harnesses**: Shared instructions, skills, hooks and MCP connections so Claude Code, Codex, Cursor, Copilot and other agents work the same way in every repository.
- **Free tool requests**: Missing a tool, connector or skill? We build it for free within 5 days.

## Tested before it ships

Everything we build is tested against plain AI on your real questions before it reaches your teams, the way every tool on the Aroai board is. What does not give a better answer does not ship.

## Yours to run

You get the code or the connection, the instructions and the tests, and a short handover for the people who look after it. Tools that suit everyone can join the Aroai board, so your teams use them alongside the rest.

## How a build runs

1. **Map the job** Agree the job, the sources and systems it needs, and who reviews the result.
2. **Build and test** Build the server, tool, skill or harness and test it against plain AI on real questions.
3. **Connect and hand over** Connect it to the AI your teams use and hand over the code, instructions and tests.
