Open-source AI agent harness in native Rust — GUI, CLI, headless, and webapp from one binary. Multi-provider, MCP, skills, plugins, agent teams.

thClaws is an open-source AI agent harness built in Rust that provides a complete workspace for running autonomous agents across GUI, CLI, headless, and web interfaces from a single binary. It supports multiple LLM providers (Anthropic, OpenAI, Google, DeepSeek, and 20+ others totaling 1,100+ models), integrates MCP servers for extensibility, and enables agent teams to coordinate on complex tasks. Developers can build custom agents with skills, plugins, browser automation, media generation, and knowledge bases while maintaining full control through filesystem sandboxing and permission controls.

Key Features

Multi-interface deployment: native desktop GUI, CLI REPL, headless scripting, and web server from one Rust binary
1,100+ models across 27 providers including Anthropic, OpenAI, Google Gemini, DeepSeek, Ollama, and OpenRouter
Model Context Protocol (MCP) support for stdio and HTTP-Streamable servers with OAuth 2.1+PKCE
Agent teams with concurrent multi-process coordination, shared mailbox, task queues, and dedicated worktrees
Knowledge Management System (KMS) with grep-based retrieval and /dream command for session mining
OS-level bash confinement using macOS Seatbelt, Linux Landlock, and bubblewrap for filesystem security
Media Studio for text-to-image, image-to-video generation across Gemini, OpenAI, Qwen, and Veo providers
Enterprise policy enforcement with OIDC SSO, LLM gateway routing, extension allow-lists, and payload-free audit trails

thClaws — FAQ

What is thClaws?+

thClaws is an open-source AI agent harness written in Rust that runs autonomous agents with support for multiple LLM providers, MCP servers, skills, and plugins. It provides GUI, CLI, headless, and web server interfaces from a single binary, enabling developers to build and deploy AI agents across platforms.

How do I install thClaws?+

Download pre-built binaries for macOS, Windows, or Linux from the GitHub releases page or thclaws.ai/downloads, or build from source by cloning the repository and running ./scripts/build.sh (requires Rust, Node.js 20+, and pnpm 10+). On Linux servers without GUI libraries, use --cli mode to avoid webkit2gtk dependencies.

Which AI clients and platforms does thClaws work with?+

thClaws is a standalone agent runtime, not a plugin for other clients. It provides OpenAI-compatible and Anthropic-compatible HTTP APIs when run with --serve, allowing tools that use the OpenAI or Anthropic SDK to connect to it. It also bridges agents into Telegram, LINE, and Facebook Messenger, with Discord, Slack, and WhatsApp adapters in development.

Do I need API keys to use thClaws?+

Yes, you need API keys for cloud LLM providers like Anthropic, OpenAI, or OpenRouter. Keys are stored in your OS keychain (macOS Keychain, Windows Credential Manager, Linux Secret Service) or a .env file. You can run entirely offline using Ollama with local models, which requires no API keys.

Is thClaws free and open source?+

Yes, thClaws is dual-licensed under MIT and Apache 2.0, making it free to use, modify, and distribute. Enterprise Edition features (org policy enforcement, SSO, audit trails) use the same open-source binary but require a signed policy file and commercial support from ThaiGPT Co., Ltd.

How do I add MCP servers or skills to thClaws?+

Use /mcp add <name> <url> to connect MCP servers, or /skill install <github-url> to install skills from repositories. Skills are folders with SKILL.md files placed in .thclaws/skills/, and MCP server configurations go in .mcp.json or .thclaws/mcp.json following the Model Context Protocol specification.

How do I install thClaws?+

Open the source repository on GitHub and follow its README. thClaws is a agent — MCP Agents Market links you directly to the official repo.

Is thClaws free?+

thClaws is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
