TrustClaw by Composio
Composio (ComposioHQ)
Self-hostable personal AI agent with vector memory, Composio tool integrations, sandboxed execution, OAuth, and Telegram support.
Key features
- OAuth-Only Credential Management: Connects to third-party services via OAuth so no plaintext API keys or passwords are stored locally; credentials are delegated and can be revoked centrally.
- Vector Memory (pgvector): Persistent embedding-backed memory using Postgres + pgvector to store and retrieve contextual data for multi-turn conversations and longer-term personalization.
- Sandboxed Remote Execution: Runs every action in an isolated cloud sandbox that is created per-task and destroyed afterward, reducing risk from untrusted code or tools.
- Composio Tool Integrations: Integrates with Composio’s tool ecosystem and delegated auth to access 1,000+ apps and managed tool surfaces without manual API key setup.
- Vercel AI Gateway Integration: Routes LLM and embedding requests through the Vercel AI Gateway so users can operate without direct Anthropic/OpenAI keys and benefit from hosted inference paths.
- Telegram Bot & Scheduling: Provides a Telegram bot for chat access and supports cron/recurring tasks so the agent can run automated workflows and scheduled actions while users sleep.
- Self-Hostable Deployment & CLI: Designed for quick self-hosting with a Vercel deploy flow and CLI scripts (deploy-in-2-minutes experience), plus a dev workflow for local deployment using provided env examples.
