filter_table_names
AI agents call filter_table_names to retrieve information from MCP-Python without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name implies a read-only operation that retrieves a filtered list of table names from the database. Given the sibling tool 'all_table_names' which reads table names, this tool likely does the same with filtering. No side effects are expected. Empty description reduces confidence.
From the tool's definition Tool name 'filter_table_names' suggests filtering/querying table names from the database schema; description is empty and uninformative, lowering confidence.
Attacks that exploit this kind of access
filter_table_names. It is categorised as a Read tool in the MCP-Python MCP Server, which means it retrieves data without modifying state.
Register the MCP-Python 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 MCP-Python. 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 MCP-Python MCP server (rhabraken/mcp-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
