Get programming languages used in a project.
AI agents call get_project_languages to retrieve information from GitLab MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries project metadata to retrieve information about programming languages, which is a read-only operation. It retrieves data without creating, modifying, or deleting anything. The blast radius of misuse is minimal—an attacker could learn about project composition but cannot harm systems or data.
From the tool's definition Tool name 'get_project_languages' and description 'Get programming languages used in a project' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get programming languages used in a project. It is categorised as a Read tool in the GitLab MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitLab MCP Server MCP server in PolicyLayer and add a rule for get_project_languages: 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 Server. Nothing to install.
get_project_languages 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_project_languages 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_project_languages. 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_project_languages is provided by the GitLab MCP Server MCP server (skmprb/gitlab-clone-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
