AI agents call list_dbus_services to retrieve information from Sysprobe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only enumeration of D-Bus service names. It retrieves information about available services without creating, modifying, deleting, or executing operations. The filterable parameter allows selective querying but does not change any system state. This is a classic Read category operation with minimal security risk, appropriate for diagnostic purposes.
From the tool's definition Tool name 'list_dbus_services' and description 'List D-Bus names on the session or system bus (filterable)' indicate a query/retrieval operation with no modifications.
Attacks that exploit this kind of access
List D-Bus names on the session or system bus (filterable). It is categorised as a Read tool in the Sysprobe MCP Server, which means it retrieves data without modifying state.
Register the Sysprobe MCP server in PolicyLayer and add a rule for list_dbus_services: 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 Sysprobe. Nothing to install.
list_dbus_services 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_dbus_services 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_dbus_services. 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_dbus_services is provided by the Sysprobe MCP server (raindancer118/sysprobe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
