Mintlify Index gives coding agents one search layer for technical knowledge. It routes questions about indexed products to publisher-maintained documentation hosted on Mintlify and uses web search for questions outside that corpus. Use Index through the public MCP server or the access-controlled REST API.
  • MCP server: Connect an AI tool and let it retrieve source-cited context while you work. Publicly available. Does not require an API key.
  • REST API: Search for ranked sources, assemble context within a token budget, or retrieve the contents of selected results. Access-controlled. Requires an Index API key.

​
Get started

REST API

Use search, context, and contents in an application or agent.

How Index retrieves context

1

Route the question

Index identifies whether the question concerns a product in its documentation corpus or requires broader web results.
2

Retrieve relevant sources

Product-specific questions search current documentation from the publisher. Other questions search the web.
3

Return agent-ready context

Index ranks the results and returns source URLs with the relevant content. The MCP context tool and REST context endpoint assemble that content within a token budget.

​
Choose a retrieval operation

  • context: Use this for most agent tasks. It returns a compact set of cited source material in one request.
  • search: Use this when your application needs ranked results and controls which sources to read. Available through the REST API.
  • contents: Use this after search to retrieve content for selected Mintlify result IDs or result URLs. Available through the REST API.
