THE RISK

Medium Risk

Why coordinate_checkpoint needs a policy

This tool creates or stores checkpoint data across multiple backend systems. While checkpoints are generally reversible (can be rolled back or deleted), the tool modifies state across multiple coordinated systems (Memory, Filesystem, Git, Database), making it a Write operation with significant blast radius. It is not Destructive because checkpoints are not permanent deletions.

From the tool's definition Tool name 'coordinate_checkpoint' combined with description 'Create a coordinated checkpoint across multiple MCPs' indicates data creation/modification.

POLICY

How to control coordinate_checkpoint

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

policy.json

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

coordinate_checkpoint 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 MCP Conductor — 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 coordinate_checkpoint

What does the coordinate_checkpoint tool do? +

Create a coordinated checkpoint across multiple MCPs. It is categorised as a Write tool in the MCP Conductor MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on coordinate_checkpoint? +

Register the MCP Conductor MCP server in PolicyLayer and add a rule for coordinate_checkpoint: 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 MCP Conductor. Nothing to install.

What risk level is coordinate_checkpoint? +

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

Can I rate-limit coordinate_checkpoint? +

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

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

coordinate_checkpoint is provided by the MCP Conductor MCP server (lutherscottgarcia/mcp-conductor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MCP Conductor tool call.

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