get_file
AI agents call get_file to retrieve information from Kepler MCP GitLab Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves file data from a GitLab repository with no side effects. Reading file content is a safe, non-destructive operation. Severity is low because exposure of this capability poses minimal risk—fetching files does not modify state, delete data, execute code, or commit financial transactions.
From the tool's definition Tool name is 'get_file', which conventionally retrieves file content without modification. No description provided, but naming pattern and sibling context (create_file, create_merge_request, etc.) indicate this fetches data from GitLab.
Attacks that exploit this kind of access
get_file. It is categorised as a Read tool in the Kepler MCP GitLab Server MCP Server, which means it retrieves data without modifying state.
Register the Kepler MCP GitLab Server MCP server in PolicyLayer and add a rule for get_file: 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 Kepler MCP GitLab Server. Nothing to install.
get_file 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 get_file 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 get_file. 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.
get_file is provided by the Kepler MCP GitLab Server MCP server (ryan-rbw/kepler-mcp-gitlab-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
