identity_create_oauth2_provider
AI agents use identity_create_oauth2_provider to create or update resources in Prometheus MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Prometheus MCP Server environment.
The tool name contains 'create', indicating it creates a new OAuth2 provider identity configuration. This is a Write operation as it establishes a new identity provider. However, the description is empty, so confidence is lowered. Creating an OAuth2 provider could have significant security implications (authentication/authorization infrastructure), warranting high severity.
From the tool's definition Tool name: identity_create_oauth2_provider — 'create' suggests writing/creating a new OAuth2 provider configuration
Documented attack patterns abuse exactly the kind of access identity_create_oauth2_provider gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Prometheus MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for identity_create_oauth2_provider:
{
"version": "1",
"default": "deny",
"tools": {
"identity_create_oauth2_provider": {
"limits": [
{
"counter": "identity_create_oauth2_provider_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}identity_create_oauth2_provider 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.

identity_create_oauth2_provider. It is categorised as a Write tool in the Prometheus MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Prometheus MCP Server MCP server in PolicyLayer and add a rule for identity_create_oauth2_provider: 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 Prometheus MCP Server. Nothing to install.
identity_create_oauth2_provider 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 identity_create_oauth2_provider 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 identity_create_oauth2_provider. 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.
identity_create_oauth2_provider is provided by the Prometheus MCP Server MCP server (awslabs.prometheus-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Prometheus MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
