What github_check_token_scopes does on Github
AI agents call github_check_token_scopes to retrieve information from Github without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why github_check_token_scopes is rated Low
This tool performs a passive inspection of token capabilities. It retrieves information about what scopes a GitHub token possesses, which is a read operation with no side effects. It does not modify, execute, create, delete, or move any data or resources. The blast radius is minimal—misuse would only surface token capability information that the holder already implicitly possesses.
From the tool's definition Tool name 'github_check_token_scopes' and description 'Check whether the current token has the required (classic) scopes' indicate a read-only inspection operation that queries token metadata without modifying anything.
Attacks that exploit this kind of access
The rule that runs github_check_token_scopes safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Github, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For github_check_token_scopes, this is the rule to start with:
github_check_token_scopes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Github, apply this rule, and every github_check_token_scopes call is checked against it from then on.
Questions about github_check_token_scopes
Check whether the current token has the required (classic) scopes. It is categorised as a Read tool in the Github MCP Server, which means it retrieves data without modifying state.
Register the Github MCP server in PolicyLayer and add a rule for github_check_token_scopes: 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 Github. Nothing to install.
github_check_token_scopes 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_check_token_scopes 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_check_token_scopes. 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_check_token_scopes is provided by the Github MCP server (dkeeno/github-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
