Retrieve and return a list containing information about tables in specified schema, if empty uses connection default
AI agents call podbc_get_tables to retrieve information from MCP PyODBC Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries database schema metadata to list available tables. It performs a read-only retrieval operation with no side effects, no data modification, no code execution, and no destructive operations. The blast radius of misuse is minimal—an attacker gains only knowledge of table structure, which is typically non-sensitive metadata and would not directly compromise data integrity or availability.
From the tool's definition Tool name 'podbc_get_tables' and description 'Retrieve and return a list containing information about tables in specified schema' indicate retrieval of metadata with no modification or deletion.
Attacks that exploit this kind of access
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 MCP PyODBC Server MCP Server, which means it retrieves data without modifying state.
Register the MCP PyODBC Server MCP server in PolicyLayer and add a rule for podbc_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 MCP PyODBC Server. Nothing to install.
podbc_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 podbc_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 podbc_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.
podbc_get_tables is provided by the MCP PyODBC Server MCP server (openlinksoftware/mcp-pyodbc-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
