AI agents call get_business_domains to retrieve information from Lucid without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes structural information about tables to infer business domains. It has no side effects, cannot modify data, and does not execute arbitrary code or commands. It is purely informational and exploratory in nature, consistent with the 'Read' category for data retrieval and querying operations.
From the tool's definition Tool name 'get_business_domains' and description 'Discover business domains by clustering tables based on schema similarity' indicate read-only analysis.
Attacks that exploit this kind of access
Discover business domains by clustering tables based on schema similarity. It is categorised as a Read tool in the Lucid MCP Server, which means it retrieves data without modifying state.
Register the Lucid MCP server in PolicyLayer and add a rule for get_business_domains: 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 Lucid. Nothing to install.
get_business_domains 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_business_domains 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_business_domains. 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_business_domains is provided by the Lucid MCP server (wiseriaai/lucid-skill). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
