Open-source TypeScript agent harness framework for building autonomous agents and AI workflows.

Agent Harness: A programmable TypeScript harness giving any model sessions, tools, skills, instructions, and filesystem access.
Autonomous Agents: Build agents that keep context across conversations and events while working toward a goal.
Workflows: Run structured automations where your code guides agent reasoning from input to finished result.
Secure Sandboxes: Give agents an isolated environment to use tools, modify files, and complete real work safely.
Durable Execution: Agents preserve progress and recover through failures and restarts.
Subagents and Tools: Delegate tasks to specialized subagents and give agents typed actions for APIs and data.
MCP and Observability: Connect tools via Model Context Protocol and monitor agents with OpenTelemetry and Braintrust.

Building Autonomous Agents: Create Claude Code or Codex-style agents that complete open-ended tasks independently.
Structured Workflows: Automate multi-step processes where code controls the agent's reasoning path.
Safe Tool Use: Run agents in a secure sandbox so they can take real actions without risk to your systems.
Local or Hosted Deployment: Run agents from the CLI during development, then deploy to a hosted runtime.
Tool Integration: Connect agents to authenticated services through MCP servers.

IS.TEAM LLC

Freemium

An infinite-canvas project board where AI coding agents connect over MCP, subscribe to cards and reply in chat alongside the team.

MCP Agent Boards: Claude, Cursor and ChatGPT connect over MCP, subscribe to a board and reply in card chat while they work, so agents behave like teammates rather than external tools.
Infinite Canvas Workspace: Tasks, notes and planning share one zoomable surface, replacing separate tracker, whiteboard and chat tools.
AI Workflow Planner: Generates and sequences the work for a board so a project can be broken down without manual ticket writing.
AI Card Assistant: A per-card helper that drafts, summarizes and answers questions inside the context of a single task.
Meeting Note Taker: Captures meeting notes using one-time workspace credits and extracts actionable tasks straight onto the board.
Per-Workspace Pricing: A flat workspace fee covering up to 15 seats on the Pro plan, so adding an engineer never triggers a surprise invoice.
Integrations and Webhooks: HMAC-signed webhooks plus Zapier and Make connections, with API access and LLM API tokens on higher tiers.
Real-Time Collaboration: Live multi-user editing with voice chat, screen sharing, sprints, time tracking and a timeline view.

Agent-Assisted Development: Letting a coding agent pick up a card, do the work and report progress in the same thread the team is reading.
Tool Consolidation: Replacing a Jira, Slack and Miro combination with a single canvas for engineering leads tired of context-switching.
Small Team Planning: Running sprints, timelines and time tracking for a startup team on a flat monthly workspace fee.
Meeting-to-Backlog Workflow: Turning recorded meeting notes into extracted, assigned board tasks without manual transcription.
Automated Intake: Collecting work through embeddable forms that create cards automatically on the right board.
Cross-Tool Automation: Wiring board events to Zapier or Make through signed webhooks so downstream systems stay in sync.
