AI agents call github_get_user_info 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 publicly or user-accessible GitHub profile information. It performs a query operation that does not create, modify, delete, or execute code. The blast radius of misuse is minimal: an agent could enumerate users or profile data, but cannot alter state, delete data, move money, or trigger external actions. Classified as Read/low severity.
From the tool's definition Tool name contains 'get' and description states 'Get information about a specific GitHub user' — a pure data retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access github_get_user_info 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_info:
{
"version": "1",
"default": "deny",
"tools": {
"github_get_user_info": {}
}
}github_get_user_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get information about a specific GitHub 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_info: 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_info 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_info 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_info. 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_info 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.
