> For clean Markdown of any page, append `.md` to the page URL.
> Documentation index: https://you.com/docs/llms.txt (section indexes: append `/llms.txt` to any section URL).
> Search these docs: Docs MCP at https://you.com/docs/_mcp/server (`searchDocs`, no API key).
> Call live You.com APIs: Product MCP at https://api.you.com/mcp (keyless `?profile=free` exposes `you-search` and `you-discover`. Research and finance use `/mcp/research`, `/mcp/finance`, or `?tools=` on `/mcp`). To pick an API or integration path, call `you-discover` on that server instead of guessing.

# Agent Harnesses

> Connect a coding agent to You.com. Web search, page fetch, and research cover docs, errors, and questions the model's training data does not.

A coding agent's training data stops at a cutoff, so current library docs, error threads, and release notes are not in the model. Web search finds those pages, fetch reads one when the agent already has the URL, and research covers a question that needs several sources. Setup for the live APIs is in the [MCP Server](/docs/agents/mcp-server) guide.
