TrueForge
TrueForge is an open-source agent runtime layer that converts large language models into operational agents.
TrueForge is an open-source agent harness designed to turn large language models into working agents by managing context engineering, the agent runtime, and agent interactions. It connects to bring-your-own models, MCP servers, sandboxes, and SQLite or Postgres databases. The TrueForge server plans turns, calls models, executes tools, pauses for human approval, and persists sessions. It includes a bundled chat UI and TypeScript SDK for custom application integration. Users can configure agents with custom skills, MCP tools, and subagents to handle complex, long-running tasks.
