Read a file's decoded text content at ref (branch, tag, or SHA).
AI agents call get_file to retrieve information from GitLab MCP 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 GitLab repository without creating, modifying, deleting, or executing anything. It is a straightforward query operation that returns data. The low severity reflects minimal risk—exposure allows an AI to read repository files, which is typically lower risk than write/execute/destructive operations, though sensitive data in files could be a concern in specific contexts.
From the tool's definition Tool name 'get_file' and description 'Read a file's decoded text content' explicitly indicates retrieval without modification. The description confirms it performs a read-only operation at a specified ref (branch, tag, or SHA) with no side effects.
Attacks that exploit this kind of access
Read a file's decoded text content at ref (branch, tag, or SHA). It is categorised as a Read tool in the GitLab MCP MCP Server, which means it retrieves data without modifying state.
Register the GitLab 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 GitLab MCP. 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 GitLab MCP server (shahabmosavi/gitlab_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
