Get file content from a repository.
AI agents call getFile to retrieve information from GitHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file content from a repository with no side effects. It does not modify, delete, or execute anything. Even if an attacker obtained access, the worst outcome would be unauthorized disclosure of code or secrets already in the repository, which is a standard read operation.
From the tool's definition Tool name 'getFile' and description 'Get file content from a repository' indicate retrieval without modification.
Attacks that exploit this kind of access
Get file content from a repository. It is categorised as a Read tool in the GitHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub MCP Server MCP server in PolicyLayer and add a rule for getFile: 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 MCP Server. Nothing to install.
getFile 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 getFile 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 getFile. 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.
getFile is provided by the GitHub MCP Server MCP server (j-nowcow/github-mcp-practice). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
