WHAT IT DOES

What pick_up does on A2A-MCP-World

AI agents use pick_up to create or update resources in A2A-MCP-World, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your A2A-MCP-World environment.

RISK

Why pick_up is rated Medium

This tool modifies the world state by transferring an item from the environment to an agent's inventory. It's reversible (items can be dropped or traded back), making it Write rather than Destructive. Misuse could allow an agent to hoard or monopolize items, but the blast radius is limited to the simulation context.

RECOMMENDED RULE

The rule that runs pick_up safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A2A-MCP-World, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pick_up, this is the rule to start with:

pick_up Rate-limited

pick_up stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about pick_up

What does the pick_up tool do? +

How do I enforce a policy on pick_up? +

Register the A2A-MCP-World MCP server in PolicyLayer and add a rule for pick_up: 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 A2A-MCP-World. Nothing to install.

What risk level is pick_up? +

pick_up is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit pick_up? +

Yes. Add a rate_limit block to the pick_up 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 pick_up completely? +

Set action: deny in the PolicyLayer policy for pick_up. 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 pick_up? +

pick_up is provided by the A2A-MCP-World MCP server (akshaytp749/A2A-MCP-World). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
