identity_update_oauth2_provider
AI agents use identity_update_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 suggests it updates OAuth2 provider identity settings, which is a reversible modification (Write category). However, the empty description creates uncertainty about the exact scope and impact. Given that OAuth2 provider changes can affect authentication flows and access control, the severity is medium. The confidence is moderate (0.65) due to the lack of descriptive documentation.

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_update_oauth2_provider:
{
"version": "1",
"default": "deny",
"tools": {
"identity_update_oauth2_provider": {
"limits": [
{
"counter": "identity_update_oauth2_provider_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}identity_update_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.
