Retrieve and return a list containing information about tables whose names contain the substring
AI agents call filter_table_names 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 retrieves and lists metadata about database tables matching a name filter. It performs a read-only query against database schema information. No data is modified, deleted, or written. The operation is a schema discovery/exploration function with minimal blast radius—it returns only table metadata filtered by name pattern.
From the tool's definition Tool name 'filter_table_names' and description 'Retrieve and return a list containing information about tables whose names contain the substring' indicate data retrieval with no modification capability.
Attacks that exploit this kind of access
Retrieve and return a list containing information about tables whose names contain the substring. 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 filter_table_names: 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.
filter_table_names 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 filter_table_names 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 filter_table_names. 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.
filter_table_names 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.
