THE RISK

Critical Risk

Why delete_context needs a policy

This tool permanently removes recorded context data without the ability to undo the operation. While the blast radius is limited to context records rather than critical system data, deletion of development activity tracking or conversation memory represents irreversible data loss.

From the tool's definition Tool name is 'delete_context' and description states 'Delete a recorded context by ID.' The verb 'delete' indicates irreversible removal of data.

Documented attack patterns abuse exactly the kind of access delete_context gives an agent:

POLICY

How to control delete_context

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_context"
  ]
}

delete_context disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register DevMind MCP — 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 delete_context

What does the delete_context tool do? +

Delete a recorded context by ID. It is categorised as a Destructive tool in the DevMind MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on delete_context? +

Register the DevMind MCP server in PolicyLayer and add a rule for delete_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 DevMind MCP. Nothing to install.

What risk level is delete_context? +

delete_context is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete_context? +

Yes. Add a rate_limit block to the delete_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 delete_context completely? +

Set action: deny in the PolicyLayer policy for delete_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 delete_context? +

delete_context is provided by the DevMind MCP server (jochenyang/devmind-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every DevMind MCP tool call.

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