Get the database schema showing all tables, their columns, and data types. Essential for understanding the database structure before writing custom queries.
AI agents call get_schema to retrieve information from Mcp Strategy Research Db without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves schema metadata (tables, columns, data types) from a SQLite database. It is purely informational and read-only—it does not modify, delete, execute, or trigger any external operations. While the schema information could theoretically be used to craft harmful queries, the tool itself performs no actions beyond querying and returning structural data.
From the tool's definition Tool name 'get_schema' and description 'Get the database schema showing all tables, their columns, and data types' indicate a retrieval operation that returns metadata about the database structure with no side effects.

Get the database schema showing all tables, their columns, and data types. Essential for understanding the database structure before writing custom queries. It is categorised as a Read tool in the Mcp Strategy Research Db MCP Server, which means it retrieves data without modifying state.
Register the Mcp Strategy Research Db MCP server in PolicyLayer and add a rule for get_schema: 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 Mcp Strategy Research Db. Nothing to install.
get_schema 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_schema 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_schema. 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_schema is provided by the Mcp Strategy Research Db MCP server (locupleto/mcp-strategy-research-db). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
