AI agents use fork_project 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.
Forking creates a new copy of a project, which is a reversible write operation. However, in a secrets management platform, forking a project could duplicate sensitive secrets and configurations, making the blast radius high if misused by an AI agent.
From the tool's definition Forks an existing project
Documented attack patterns abuse exactly the kind of access fork_project gives an agent:
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 fork_project:
{
"version": "1",
"default": "deny",
"tools": {
"fork_project": {
"limits": [
{
"counter": "fork_project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}fork_project 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.

Forks an existing project. 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.
Register the Keyshade MCP server in PolicyLayer and add a rule for fork_project: 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.
fork_project is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the fork_project 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.
Set action: deny in the PolicyLayer policy for fork_project. 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.
fork_project 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.
Start from Keyshade, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
