Return a compact summary of schemas, table/view counts, sample tables, and sample views.
AI agents call get_database_summary 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.
The tool retrieves metadata and structural information about databases without executing queries, modifying data, or triggering side effects. It falls squarely within the Read category as a schema exploration utility. Low severity because it only exposes database structure, not sensitive data extraction or code execution. High confidence because the description is clear and unambiguous.
From the tool's definition Tool returns a 'compact summary of schemas, table/view counts, sample tables, and sample views' — purely retrieval and introspection operations with no modification or execution capability.
Attacks that exploit this kind of access
Return a compact summary of schemas, table/view counts, sample tables, and sample views. 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 get_database_summary: 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.
get_database_summary 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_database_summary 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_database_summary. 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_database_summary 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.
