# Redgold for agents > Connect an existing Claude Code or Codex agent to Redgold tools. - [Hosted MCP setup](https://docs.redgold.ai/reference/mcp): Connect to https://api.redgold.ai/api/mcp with an account API key for API discovery, calls, data and pipelines; no local binary required. - [Setup skill](https://redgold.ai/skill.md): Install redgold, rac and rci, configure an existing API key, install persistent skills, verify access and update safely. - [Copyable setup prompt](https://redgold.ai/agent-setup.txt): Give this to your agent. It contains no credentials. - [Search skill](https://redgold.ai/skills/rac-research/SKILL.md): Search providers, quotes, spending caps and evidence links. - [Remote build skill](https://redgold.ai/skills/rac-build/SKILL.md): Configure an authorized builder, run Cargo or pnpm and retrieve outputs. - [Public documentation](https://docs.redgold.ai/llms.txt): Current public documentation index. - [Full documentation](https://docs.redgold.ai/llms-full.txt): Public documentation as Markdown. - [Account signup](https://redgold.ai/signup): Create an account if you do not already have one. An existing API key is the primary setup path. Search and build permissions are checked separately. x402 currently supports development search/fetch payments, not account or workspace creation. Do not infer access from a username or payment.
