Get the schema of the given table
AI agents call get_schema to retrieve information from Awslabs Valkey without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Schema inspection is a read-only operation with no side effects. It queries structural information about a table and poses minimal risk if misused by an AI agent, as it cannot modify, delete, or execute operations. The sibling tools (including administrative and case management functions) suggest this is part of a broader AWS/database management server, where schema retrieval is a safe informational operation.
From the tool's definition Tool name is 'get_schema' and description states 'Get the schema of the given table' — this retrieves schema metadata without modifying data or executing code.
Attacks that exploit this kind of access
Get the schema of the given table. It is categorised as a Read tool in the Awslabs Valkey MCP Server, which means it retrieves data without modifying state.
Register the Awslabs Valkey 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 Awslabs Valkey. 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 Awslabs Valkey MCP server (awslabs.valkey-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
