AI agents invoke provision_resources to trigger actions in Neptune MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The tool name 'provision_resources' strongly implies creating/spinning up cloud infrastructure resources on AWS. Provisioning typically involves executing infrastructure changes (creating VMs, databases, networks, etc.) which are external operations with significant blast radius.
From the tool's definition Tool name 'provision_resources' on a server that 'deploys applications to AWS' and has sibling tools like 'deploy_project', 'delete_project', 'add_new_resource'
Documented attack patterns abuse exactly the kind of access provision_resources gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Neptune MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for provision_resources:
{
"version": "1",
"default": "deny",
"tools": {
"provision_resources": {
"limits": [
{
"counter": "provision_resources_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}provision_resources stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

provision_resources. It is categorised as a Execute tool in the Neptune MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Neptune MCP Server MCP server in PolicyLayer and add a rule for provision_resources: 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 Neptune MCP Server. Nothing to install.
provision_resources is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the provision_resources 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 provision_resources. 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.
provision_resources is provided by the Neptune MCP Server MCP server (shuttle-hq/neptune-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Neptune MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
