Get available analysis rules for a specific language
AI agents call get_language_rules to retrieve information from GitLab Review MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration or metadata about analysis rules for code quality checks. It performs a simple lookup/query operation without modifying data, executing code, or triggering external actions. The blast radius of misuse is minimal—an agent could at most retrieve information about what rules are available for different languages, which poses no security risk.
From the tool's definition Tool name 'get_language_rules' and description 'Get available analysis rules for a specific language' indicate a retrieval operation with no side effects. It fetches metadata about code analysis rules.
Attacks that exploit this kind of access
Get available analysis rules for a specific language. It is categorised as a Read tool in the GitLab Review MCP MCP Server, which means it retrieves data without modifying state.
Register the GitLab Review MCP server in PolicyLayer and add a rule for get_language_rules: 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 Review MCP. Nothing to install.
get_language_rules 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_language_rules 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_language_rules. 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_language_rules is provided by the GitLab Review MCP server (lininn/gitlab-review-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_language_rules is one line of GitLab Review's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
