What get_capabilities does on Businys
AI agents call get_capabilities to retrieve information from Businys without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_capabilities is rated Low
This is a capability discovery/introspection tool that queries metadata about available tools and permissions. It retrieves information only and cannot modify, execute, delete, or commit financial actions. The blast radius of misuse is minimal—an agent might learn about available tools earlier than intended, but this poses no direct risk. Classified as Read.
From the tool's definition Tool name 'get_capabilities' and description 'Discover which tools, practices, and resources are available' and 'Returns the list of allowed tools' indicate pure data retrieval with no modifications, side effects, or operations.
Attacks that exploit this kind of access
The rule that runs get_capabilities safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Businys, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_capabilities, this is the rule to start with:
get_capabilities is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Businys, apply this rule, and every get_capabilities call is checked against it from then on.
