WHAT IT DOES

What agent_run does on EasyBits

AI agents invoke agent_run to trigger actions in EasyBits. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why agent_run is rated High

Executes arbitrary code with root privileges and internet access in isolated VM environment.

From the tool's definition Start managed Claude agent in Firecracker microVM, root, internet egress, Bash/Read/Write

RECOMMENDED RULE

The rule that runs agent_run safely

PolicyLayer is an MCP gateway: it sits between your AI agents and EasyBits, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For agent_run, this is the rule to start with:

agent_run Rate-limited

agent_run stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about agent_run

What does the agent_run tool do? +

Start a managed Claude agent (Claude Agent SDK loop) inside a fresh Firecracker microVM. By default the agent has Bash/Read/Write/Edit/Glob/Grep/WebFetch (interactive/session tools like Agent, AskUserQuestion, Skill, TodoWrite are denied — this is a headless VM) and full root with open internet egress. EasyBits supplies Anthropic credentials by default (OAuth/Max-plan token preferred, API key fallback) and bills the run; switch to BYOK (Bring Your Own Key) by registering your own credential via. It is categorised as a Execute tool in the EasyBits MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on agent_run? +

Register the EasyBits MCP server in PolicyLayer and add a rule for agent_run: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches EasyBits. Nothing to install.

What risk level is agent_run? +

agent_run is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit agent_run? +

Yes. Add a rate_limit block to the agent_run rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block agent_run completely? +

Set action: deny in the PolicyLayer policy for agent_run. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides agent_run? +

agent_run is provided by the EasyBits MCP server (@easybits.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
