Drop-in OpenAI **and Anthropic** API server that routes through agent CLIs (currently [Claude Code](https://docs.anthropic.com/en/docs/claude-code)).

Compatibility note: `claude-relay` remains available as a compatibility package/command alias.

Why

You have tools that speak the OpenAI or Anthropic API. You have Claude Code with its tools, MCP servers, and agentic capabilities. **agent-relay** bridges the two — point any compatible client at it and every request flows through `claude -p` under the hood.

• Use Claude Code from any OpenAI or Anthropic client — Cursor, Continue, aider, LangChain, custom scripts
• Keep Claude Code's superpowers — tool use, MCP servers, file access, shell execution
• Zero config — if claude works on your machine, so does this
• Real token usage — reports actual token counts from Claude (not zeros)
• Token-level streaming — uses --include-partial-messages for true real-time deltas
