Search for GitLab projects
AI agents call search_repositories 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 and returns information about GitLab projects based on search criteria. It performs no modifications, deletions, or external state changes. The lowest severity applies because even if an AI agent misuses this to enumerate all projects, the worst outcome is information disclosure rather than data loss, unauthorized changes, or financial impact.
From the tool's definition Tool name is 'search_repositories' with description 'Search for GitLab projects'. The verb 'search' indicates a read-only query operation that retrieves and lists data without modification or side effects.
Attacks that exploit this kind of access
Search for GitLab projects. 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 search_repositories: 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.
search_repositories 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 search_repositories 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 search_repositories. 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.
search_repositories is provided by the GitLab MCP Server MCP server (therealchristhomas/gitlab-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
