Retrieve and return a list containing information about tables in specified schema, if empty uses connection default
AI agents call get_tables to retrieve information from OpenLink MCP Server for ODBC without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries database metadata and returns information without creating, modifying, deleting, or executing arbitrary operations. It is purely informational about schema structure, making it a safe Read operation with minimal blast radius if an agent misuses it.
From the tool's definition Tool retrieves a list of tables in a schema with no modification capability. Description states 'Retrieve and return' indicating a query-only operation.

Retrieve and return a list containing information about tables in specified schema, if empty uses connection default. It is categorised as a Read tool in the OpenLink MCP Server for ODBC MCP Server, which means it retrieves data without modifying state.
Register the OpenLink MCP Server for ODBC MCP server in PolicyLayer and add a rule for get_tables: 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 OpenLink MCP Server for ODBC. Nothing to install.
get_tables 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_tables 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_tables. 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_tables is provided by the OpenLink MCP Server for ODBC MCP server (pvsmark/pvs-odbc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
