get_global_context_data

THE RISK

Low Risk

Why get_global_context_data needs a policy

The tool performs a read-only operation that queries and returns data from a global context store. There is no indication of data modification, deletion, code execution, or financial impact. The retrieval of context data poses minimal risk as it simply exposes existing state information used for testing and development purposes within the MockLoop MCP server environment.

From the tool's definition Tool name 'get_global_context_data' and description 'Retrieves data from the global context' indicate a data retrieval operation with no modification or side effects.

POLICY

How to control get_global_context_data

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 get_global_context_data:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_global_context_data": {}
  }
}

get_global_context_data is read-only, so it stays allowed — but 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 get_global_context_data

What does the get_global_context_data tool do? +

Retrieves data from the global context. It is categorised as a Read tool in the MockLoop MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_global_context_data? +

Register the MockLoop MCP Server MCP server in PolicyLayer and add a rule for get_global_context_data: 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 get_global_context_data? +

get_global_context_data is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_global_context_data? +

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

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

get_global_context_data 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.
