THE RISK

Critical Risk

Why manage_session needs a policy

The tool explicitly supports deleting sessions, which is an irreversible destruction of session data. Combined with the ability to end sessions (potentially losing tracked development activity and context), the most severe applicable category is Destructive. Misuse by an AI agent could result in permanent loss of development session history and context.

From the tool's definition 'end, delete, or end and delete' — the delete operation irreversibly removes session data; ending a session may also permanently close tracked state

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

POLICY

How to control manage_session

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 manage_session:

policy.json

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

manage_session 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 manage_session

What does the manage_session tool do? +

Manage development sessions: end, delete, or end and delete. 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 manage_session? +

Register the DevMind MCP server in PolicyLayer and add a rule for manage_session: 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 manage_session? +

manage_session 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 manage_session? +

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

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

manage_session 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.
