Muster

agent harness · governed execution

An agent harness for AI systems that have to keep running.

Muster wraps model calls, tools, memory, channels, MCP servers, and evals in one governed run loop so agents do not leak context, hide token spend, or learn without tests.

Controls

What the harness owns.

Scoped memory

Tenant, workspace, user, role, and session lanes backed by indexed retrieval and leakage tests.

Token ledger

Every run records usage and flags replay waste so cost does not disappear into provider logs.

Tool policy

Capability packs and MCP servers declare permissions, secrets, result caps, and setup requirements.

Channel gateway

Terminal, web, Telegram, Slack, Google Chat, Teams, Discord, and WhatsApp surfaces enter the same envelope.

Eval-gated learning

Feedback becomes fixtures before behavior is promoted into durable agent behavior.

Where it fits

Use Muster around your agent framework, not only instead of one.

Muster is useful when your team already has prompts, tools, MCP servers, business apps, or model routes and needs governance around the run: memory boundaries, token visibility, setup checks, and reproducible eval evidence.
