# Fous

> Fous retrieves web data through reusable workflows. Describe what to retrieve from a website once, then change the inputs to get new results in Fous Studio or through the API, or from an AI assistant over MCP.

- Run any workflow again with new inputs: in Fous Studio, through the API or from an AI assistant over MCP.
- Build a workflow in Fous Studio. Builds submitted with network sharing on are free and may contribute a general public version. With sharing off, builds cost 100 credits when ready.
- Finding the right workflow is free. Each completed workflow run uses 1 credit from your organization. Failed runs without a completed receipt are free; completed work can remain charged if delivery is interrupted.

## Use Fous from an AI agent

- [Agent guide](https://fous.com/llms-full.txt): connect the MCP server, call a workflow, credits and errors; then every workflow with its operations
- [MCP server](https://api.fous.com/mcp): remote MCP server (Streamable HTTP) for Claude Code, Claude Desktop, Cursor, VS Code, Codex and any MCP client. Send `Authorization: Bearer <Fous API key>`. Tools: `fous_search_workflows`, `fous_get_workflow`, `fous_run_workflow`, `fous_run_action`, `fous_get_run`; start with `fous_search_workflows`. Claude Code: `claude mcp add --scope user --transport http fous https://api.fous.com/mcp --header "Authorization: Bearer ${FOUS_API_KEY:?Set FOUS_API_KEY to your Fous API key}"`
- [One workflow as an MCP server](https://api.fous.com/mcp/workflows/hacker-news): `https://api.fous.com/mcp/workflows/{name}` gives each method of one workflow its own typed tool; `{name}` is the name in the workflow’s page URL
- [OpenAPI](https://api.fous.com/openapi.json): `POST https://api.fous.com/v1/query` with `{"api":"@hacker-news","operation":"list_front_page","input":{"list_name":"show_hn","max_results":5}}` runs one workflow with exact inputs and returns its data in `data.output`
- [Fous API keys](https://app.fous.com/keys): in Fous Studio, open Developers at the bottom of the screen, turn on Developer mode, then go to API keys. Send a key as `Authorization: Bearer $FOUS_API_KEY` from server-side code or the agent’s environment
- [Docs for agents](https://docs.fous.com/llms.txt): guides and API reference as Markdown
