Retrieve and return a dictionary containing the definition of a table, including column names, data types, nullable,
AI agents call podbc_describe_table 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 is a metadata query operation that returns structural information about a table schema. It has no side effects, does not execute code or queries against data, does not modify anything, and does not delete anything. The blast radius of misuse is minimal—an attacker could learn about table structure to plan further attacks, but the tool itself performs only read-only introspection.
From the tool's definition Tool name 'podbc_describe_table' and description indicate it retrieves table metadata (column names, data types, nullable properties) without modifying or executing operations on data.
Attacks that exploit this kind of access
Retrieve and return a dictionary containing the definition of a table, including column names, data types, nullable,. 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_describe_table: 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_describe_table 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_describe_table 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_describe_table. 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_describe_table 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.
