# Documentation

Welcome to the Viktor docs. Viktor is an AI employee that lives in Slack and Microsoft Teams, connects to 9,000+ integrations, and takes action across your entire tool stack. Build on top of him with the Public API, MCP server, or OpenAI- and Anthropic-compatible API.

## Developers

[Viktor Public API](/content/docs/public-api/index.html)  
Create Viktor threads, run tasks, continue conversations, and download result files from your own applications.

[Viktor MCP Server](/content/docs/mcp-server/index.html)  
Connect an MCP-compatible agent to Viktor with streamable HTTP and a scoped Viktor API key.

[OpenAI & Anthropic Compatible API](/content/docs/chat-completions/index.html)  
Drive Viktor agent runs with the OpenAI or Anthropic SDKs you already use — no new client code required.
