Get a list of tables, optionally filtered by database it belongs to. Use fields parameter to get only necessary fields. Use cursor-based pagination to limit the number entries in the list using limit and before or after query params.
AI agents call get_list_of_tables to retrieve information from Mcp Openmetadata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about tables from OpenMetadata without modifying, executing operations on, or deleting any data. It is purely a read operation that queries and returns information. The blast radius of misuse is minimal—an agent could retrieve metadata it shouldn't access, but cannot alter or execute anything. This is typical low-severity Read access.
From the tool's definition Tool description states it 'Get[s] a list of tables' with filtering and pagination capabilities. The server description indicates this enables 'searching and retrieving metadata from OpenMetadata, including tables, columns, sample data, and ownership…
Attacks that exploit this kind of access
Get a list of tables, optionally filtered by database it belongs to. Use fields parameter to get only necessary fields. Use cursor-based pagination to limit the number entries in the list using limit and before or after query params. It is categorised as a Read tool in the Mcp Openmetadata MCP Server, which means it retrieves data without modifying state.
Register the Mcp Openmetadata MCP server in PolicyLayer and add a rule for get_list_of_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 Openmetadata. Nothing to install.
get_list_of_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_list_of_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_list_of_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_list_of_tables is provided by the Mcp Openmetadata MCP server (pfldy2850/mcp-openmetadata). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
