Manually refresh GitHub token (re-reads gh CLI config and env vars).
AI agents call github_refresh_token to retrieve information from Android MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool re-reads configuration files and environment variables to refresh an in-memory token. It does not write, execute commands with side effects, or modify any data — it only reads existing auth config. Severity is low since misuse at most exposes token values already stored on the device.

Attacks that exploit this kind of access
Manually refresh GitHub token (re-reads gh CLI config and env vars). It is categorised as a Read tool in the Android MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Android MCP Server MCP server in PolicyLayer and add a rule for github_refresh_token: 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 Android MCP Server. Nothing to install.
github_refresh_token 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_refresh_token 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_refresh_token. 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_refresh_token is provided by the Android MCP Server MCP server (wujie272/android-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
