Why create_agent_context needs a policy

This tool creates a new agent context, which is a reversible data creation operation. It does not execute arbitrary code, delete data irreversibly, or move money. While the exact schema of what 'agent context' entails is not detailed, the creation of configuration/context objects for AI agent integration is fundamentally a Write operation.

From the tool's definition Tool name 'create_agent_context' and description 'Creates an agent context for AI agent integration' indicate data creation.

POLICY

How to control create_agent_context

PolicyLayer is an MCP gateway — it sits between your AI agents and MockLoop MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_agent_context:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_agent_context": {
      "limits": [
        {
          "counter": "create_agent_context_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_agent_context 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.

Create a free account and register MockLoop MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_agent_context

What does the create_agent_context tool do? +

Creates an agent context for AI agent integration. It is categorised as a Write tool in the MockLoop MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_agent_context? +

Register the MockLoop MCP Server MCP server in PolicyLayer and add a rule for create_agent_context: 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 MockLoop MCP Server. Nothing to install.

What risk level is create_agent_context? +

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

Can I rate-limit create_agent_context? +

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

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

create_agent_context is provided by the MockLoop MCP Server MCP server (mockloop/mockloop-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MockLoop MCP Server tool call.

Start from MockLoop MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
