How do I configure the rate_limit on a route in Acme's API? Need to support burst windows.
Searched and read 2 documents

PATCH the route with rate_limit. Each route has its own bucket scoped to the path; authenticated and anonymous traffic are metered separately.

curl -X PATCH https://api.acme.dev/v1/routes/checkout \
  -d '{"rate_limit":{"requests":100,"per":"minute","burst":50}}'

The burst field caps transient surges. When clients exceed the limit, the API returns 429 with a Retry-After header.

Product documentation in AI tools

Help developers check answers against your docs

An AI client can search your docs, read matching documents when it needs more context, and answer from that text. Biel hosts the connection and keeps it tied to the sources your team maintains.
i.

Find the right information

Your AI assistant can find relevant information across your documentation, uploaded files, and code repositories.

ii.

Read the full indexed document

When a passage needs more context, the client can retrieve the complete indexed text with source references, without opening the original site.

iii.

Maintain one project index

The website assistant and MCP endpoint retrieve from the same sources. Refresh them using the controls and schedule available in your plan.

Connect your AI tools

Use your technical docs in Claude and Codex

Biel is a hosted MCP server for technical documentation. Connect your project endpoint so an AI assistant can search your maintained guides and read the indexed text before answering.

Connect technical documentation to Claude Code

Add your Biel project endpoint to Claude Code. Ask it to check your API reference, SDK guides, or troubleshooting docs while it works on an integration.

For example: “Search our product docs for the authentication flow, then use the documented method in this client.”

Connect docs to Claude Code

Connect technical documentation to Codex

Add the same hosted endpoint to Codex. Give it access to the product documentation it needs to build, review, or troubleshoot an integration.

For example: “Read our pagination reference before updating this API client, and include the source you used.”

Connect docs to Codex

Using Claude Desktop or another MCP client? See the MCP connection guide. Client settings determine when tools are called. Biel supplies indexed documentation, while the client generates its response.

Compatible tools

One endpoint for supported MCP clients

Connect the hosted endpoint to the tools your team already uses. Client permissions and authentication requirements apply.

Claude Code

Look up your product docs while coding in the terminal or editor.

Codex

Give Codex your product docs to help it build and review integrations.

ChatGPT

Ask about your public product docs through a custom MCP connection in ChatGPT.

Cursor

Find relevant guides and API references without leaving your editor.

GitHub Copilot in VS Code

Let Copilot agents look up your docs through VS Code’s built-in MCP support.

Google Antigravity

Bring your product docs into coding tasks in Antigravity’s editor or CLI.

How it works

Connect your docs, then add the endpoint

Biel hosts the MCP server. Connect your sources, copy the project endpoint, and add it to a supported client.
  1. 01

    Connect your docs

    Paste your documentation URL. Biel indexes the sources you connect so AI tools can retrieve relevant documentation.

    Create an account
  2. 02

    Get your MCP endpoint

    Plans with MCP include a hosted server URL for your project. Biel operates the endpoint, so you do not need to deploy a server.
    https://app.biel.ai/mcp/<project>
  3. 03

    Connect a compatible AI tool

    Add the URL to a supported MCP client. It retrieves from the same indexed sources as your Biel assistant.
Supported platforms

Connect multiple sources to one project

Index supported documentation sites, repositories, and knowledge sources, then expose that project through one MCP endpoint.

Questions about MCP

Which plan includes MCP?

Hosted MCP starts on Professional at $150/month for public projects. Private MCP requires Business or Enterprise. Compare plans and usage limits.

What is the Model Context Protocol (MCP)?

MCP is an open protocol for connecting AI assistants to tools and data sources. Biel uses it to make your indexed documentation available to compatible AI clients.

Do I need to self-host the MCP server?

No. Biel hosts your project endpoint on plans with MCP. Copy the full URL from your project and add it to a compatible client.

Which AI tools support MCP today?

Biel works with remote MCP clients such as Claude Code, Codex, Cursor, Copilot in VS Code, and Antigravity. ChatGPT can connect to public projects, subject to its workspace permissions.

How does the MCP server stay in sync with my docs?

Biel refreshes indexed sources on a schedule or on demand. The MCP endpoint and website assistant retrieve from the same project index.

Can multiple team members use the same MCP server?

Yes. Team members can connect to the same project endpoint. Public projects need no key. Private projects require a project-scoped API key, so share it only with authorized readers.

Can I expose internal docs alongside public docs?

Keep them in separate projects if they have different readers. Source permissions are not inherited by the MCP endpoint. Private MCP requires an API key on Business or Enterprise.

Does MCP replace the website assistant?

No. The widget answers questions on your website. MCP lets compatible AI tools retrieve from the same project index.

How does WebMCP differ from the hosted MCP server?

WebMCP exposes tools on a page a browser agent is visiting. Hosted MCP gives compatible AI clients a project endpoint they can use without visiting your site. Set up WebMCP for your docs.

Is WebMCP available in every browser?

No. WebMCP support is experimental and requires a supporting browser and the latest Biel widget. Existing website chat and search continue to work in browsers without WebMCP.

How is MCP access controlled?

Private endpoints require an API key on Business or Enterprise. Public endpoints need no key and should contain only public content. See the Security Overview.
