trueforge
An open-source agent harness with built-in MCP tools, skills, sandboxing, approvals, and subagents.
Who it is for: Developers needing to build and run agents, teams needing to deploy shared agent services, and teams needing to integrate agents via HTTP API, TypeScript SDK, or browser interface
Core capabilities
- Agent Execution Loop: Executes planning, model calls, and tool execution, and streams the process in real time.
- Approvals, Context, and Session Management: Pauses for manual approval before sensitive operations, manages long-running task context through subagents and compaction, and persists sessions.
- On-demand Sandbox: Configures sandbox only when the agent needs to execute code.
- API, SDK, and Chat UI: Provides HTTP API, TypeScript SDK, chat UI, React UI SDK, Server-Sent Events, OpenAPI spec, and interactive documentation.
- Local and Shared Deployment: Local mode uses single-process and SQLite; shared deployment uses Postgres, Redis, and multi-replica.
