AI agents call get_database_structure to retrieve information from MelviChat MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves structural information about a database (tables, columns, constraints, etc.). It has no side effects, cannot modify data, and poses minimal risk. The low severity reflects that schema information alone does not expose sensitive data operations and cannot cause harm when misused by an AI agent.

Obtener la estructura (esquema) de la base de datos. It is categorised as a Read tool in the MelviChat MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MelviChat MCP Server MCP server in PolicyLayer and add a rule for get_database_structure: 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 MelviChat MCP Server. Nothing to install.
get_database_structure 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_database_structure 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_database_structure. 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_database_structure is provided by the MelviChat MCP Server MCP server (melvi24/mcp-chat-ia). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
