Get the current database schema information
AI agents call get_database_schema to retrieve information from SegmentMCP 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 about the database structure. It is a read-only operation that returns information about tables, columns, and structure without executing queries, modifying data, or triggering external operations.
From the tool's definition Tool name 'get_database_schema' and description 'Get the current database schema information' indicate a retrieval operation with no modification or execution of queries.
Attacks that exploit this kind of access
Get the current database schema information. It is categorised as a Read tool in the SegmentMCP MCP Server, which means it retrieves data without modifying state.
Register the Segment MCP server in PolicyLayer and add a rule for get_database_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 SegmentMCP. Nothing to install.
get_database_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_database_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_database_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_database_schema is provided by the Segment MCP server (tejasayya/segmentmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
