Get all unique tables across all solutions
AI agents call list_tables to retrieve information from Sentinel Solutions MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates table metadata from Sentinel solutions without creating, modifying, deleting, or executing any operations. It is a straightforward query operation with no side effects. The low severity reflects minimal blast radius—an agent listing available tables cannot cause harm beyond information disclosure of non-sensitive structural metadata already documented in official repositories.
From the tool's definition Tool name 'list_tables' with description 'Get all unique tables across all solutions' indicates a retrieval operation with no modification or execution.
Attacks that exploit this kind of access
Get all unique tables across all solutions. It is categorised as a Read tool in the Sentinel Solutions MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sentinel Solutions MCP Server MCP server in PolicyLayer and add a rule for list_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 Sentinel Solutions MCP Server. Nothing to install.
list_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 list_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 list_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.
list_tables is provided by the Sentinel Solutions MCP Server MCP server (noodlemctwoodle/sentinel-solutions-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
