What sync_fork does on Keyshade

AI agents use sync_fork to create or update resources in Keyshade — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Keyshade environment.

Why sync_fork needs a policy

Syncing a fork modifies the forked project by updating it with changes from the parent. This is a reversible write operation (data is overwritten but the parent remains intact and the sync can be re-done). It does not delete data permanently, execute arbitrary code, or involve financial transactions. Severity is medium because syncing could overwrite local changes in the fork.

How to control sync_fork

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "sync_fork": {
      "limits": [
        {
          "counter": "sync_fork_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

sync_fork 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.

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

Questions about sync_fork

What does the sync_fork tool do? +

Syncs a forked project with its parent. It is categorised as a Write tool in the Keyshade MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on sync_fork? +

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

What risk level is sync_fork? +

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

Can I rate-limit sync_fork? +

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

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

sync_fork is provided by the Keyshade MCP server (keyshade-xyz/keyshade-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Keyshade tool call.

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