Where does a developer go first with an API question today? Increasingly, not to your docs. They ask Claude, Codex, or Cursor, and they trust whatever comes back.
That puts a hard question to every API team: when an AI answers about your API, is it reading your documentation, or guessing?
We've spent the last two months making sure it's reading. Here's what shipped, and where it's heading.
Projects ship with a built-in Docs MCP server at /mcp. There's nothing to build and nothing to host: point an AI tool at your docs and it can search pages, list APIs, and read endpoint details directly from the source of truth, with your RBAC rules enforced on every call.
In just two months, the server got substantially more capable:
- The newest MCP protocol. Docs MCP supports 2026-07-28 protocol version, the largest change since MCP started: a stateless core, header-based routing, cacheable tool lists, and stronger authorization. The newest AI clients and their capabilities work with your docs from day one.
- GraphQL support. The MCP tools for exploring your API catalog now cover GraphQL, not only OpenAPI. Agents can list your GraphQL APIs, browse types, and read whole schemas.
- Multi-version APIs. Projects that document several versions expose all of them, so agents answer against the version your user is actually on.
- Search that respects locales. An English question no longer pulls back the same page in every translation.
A capable server is worthless if people give up while connecting to it, so we removed the friction point by point:
- Opening
/mcpin a browser now shows a setup page with one-click setup for popular tools like VS Code and Cursor, instead of raw JSON. - Clients that support Client ID Metadata Documents connect without any registration step.
- Access tokens refresh automatically. Sessions used to expire mid-conversation and force a re-login; now they just keep working.
- Tools carry standard MCP annotations, so AI clients know which are safe to call without confirmation.
The whole thing is configurable in one place, and you can put a connect button right on your pages.
The next generation of agents won't wait for a human to paste in a URL. They'll discover services on their own, and a Redocly project now introduces itself:
- An MCP server card and an A2A agent card describe what your project offers, in the standard formats agents already look for.
- Agent skills go a step further: drop task-focused skill files into an
@skillsfolder, and agents follow the steps you wrote instead of guessing from reference docs.
MCP is one door into your docs; llms.txt is the other, and we made what's behind both doors better:
llms.txtoutput now includes OpenAPI code samples and response samples, and correctly rendersoneOfand discriminator schemas: exactly the parts of an API description agents used to trip over.- Custom Markdoc tags can define their own LLM rendering with
renderForLlms, with locale support. If you built a custom component, its content is no longer invisible to AI.
The AI Assistant in Reunite got smarter. It now answers from your setup: your plan and subscription, your members, your build logs, and your project configuration.
Questions that used to mean opening a support ticket and waiting for a reply now get answered instantly. Ask "why did my build fail?" and you get your build's answer, not a generic troubleshooting page. And when a human really is needed, the Contact support option appears the moment the assistant decides so.
The assistant is also how we dogfood what's coming next: its abilities are built as custom MCP tools, and the assistant itself runs as the embeddable widget. You'll meet both in the roadmap below.
Everything above assumes your docs are correct. Reviewer is how they stay correct.
Reviewer is in early access. It comments line by line as soon as a pull request opens, before the first human review. It checks:
- API descriptions. OpenAPI and AsyncAPI, breaking changes included.
- Documentation. Markdown for clarity and accuracy, cross-checked against the OpenAPI description the page refers to.
- API security. Risks framed by the OWASP API Security Top 10.
- Cross-document consistency. Pages that drifted apart and now contradict each other.
- Redocly config. Your configuration, before it reaches a deploy.
A linter checks one file against a rule set. Reviewer reads the API description and the documentation together, so it finds the places where the two disagree.
The MCP server and llms.txt make your docs something agents can read. The next wave makes them something agents can act through:
- Gateway MCP. Agents stop just reading about your API and start calling it, with your documentation as the interface. Fully opt-in: nothing is exposed unless you enable it. Your docs become the fastest way for any AI tool to integrate with your product.
- Code mode in Docs MCP. Instead of a long chain of tool calls, an agent writes a short script that runs in a sandbox and chains the calls itself. We measured both modes on a large set of documentation tasks. Code mode matched or beat the tool chain on answer quality in every task, and used 86% fewer input tokens on average, at half the cost. On the heaviest task, an audit across the whole project, it used 60 times fewer tokens.
- Custom MCP tools. Add your own tools to your project's MCP server, so agents can do what's specific to your product, not only what's built in.
- Writer. An agent that watches the signals your docs already produce (search queries, feedback, page analytics, support questions), finds the real gaps, validates them and opens pull requests with fixes. Docs that improve while you sleep.
- Embeddable AI Assistant. The assistant that answers from your docs, on your web app, with a single script tag.
Open /mcp on your Redocly project, follow the setup page, and ask your AI tool a question about your own API. That's the whole setup.
