AI agents call github_get_user_stats to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistics about a GitHub user. It is a straightforward query operation that does not modify, execute, delete, or affect any data. User statistics are public or user-accessible information, and retrieving them poses minimal security risk. The only concern would be if this enables profiling of users at scale, but a single retrieval of public user data is low-severity.
From the tool's definition Tool name 'github_get_user_stats' and description 'Get statistics about a user' indicate data retrieval with no side effects. The verb 'Get' and the read-only nature of retrieving user statistics confirm this is a retrieval operation.
Documented attack patterns abuse exactly the kind of access github_get_user_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for github_get_user_stats:
{
"version": "1",
"default": "deny",
"tools": {
"github_get_user_stats": {}
}
}github_get_user_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get statistics about a user. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for github_get_user_stats: 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 Sage MCP. Nothing to install.
github_get_user_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the github_get_user_stats 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 github_get_user_stats. 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.
github_get_user_stats is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
