# About DocStar

_About DocStar_

DocStar is API documentation for people and AI agents. Your coding agent writes the docs from your code, and DocStar publishes them as a docs site, llms.txt, a hosted MCP server and a CLI, kept in sync as your API changes.

## Why we built DocStar

More and more of the people who use an API never read its docs. They ask Claude, ChatGPT or Cursor to do the job, and the AI reads the docs and makes the calls. When the docs are missing, out of date or hard for a machine to read, the agent guesses and the call fails.

We built DocStar so that every API can be used correctly by both the people and the agents who depend on it.

## What we believe

### One source of truth

Docs, MCP and CLI are never separate projects. Publish once and every channel changes together.

### AI does the writing

You shouldn’t need a spec file or an editor to start. Your coding agent already knows your code.

### People stay in control

Agents propose and people publish. Every AI edit is a draft until someone approves it.

### Agents act for real users

An AI calls your API as the signed-in user, through your own sign-in, and never sees their credentials.

### Docs stay true

An agent is only as good as the docs it reads, so DocStar works to keep docs matched to the code.

### Your brand, not ours

Your domain on the docs site and the MCP server, and your name on the CLI.

## Who DocStar is for

### API companies and product teams

Who want customers’ AI assistants to use their API without mistakes.

### Developer experience and docs teams

Who want one place to write and publish.

### Internal platform teams

Who want their own engineers’ agents to use internal APIs safely.

## Built by Walkover

DocStar is built by Walkover, the team behind MSG91. MSG91's API reference, its MCP server and its CLI all run on DocStar, so we use what we build every day.
