List all library sources enabled for the current campaign.
AI agents call list_enabled_library to retrieve information from DM20 Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists configuration information about enabled library sources in a campaign context. It is a pure query operation that returns existing state without side effects, modifications, or triggering external actions. The blast radius of misuse is minimal—an agent could only enumerate available libraries, which is informational metadata about the campaign setup.
From the tool's definition Tool name 'list_enabled_library' and description 'List all library sources enabled for the current campaign' indicate a query/retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
List all library sources enabled for the current campaign. It is categorised as a Read tool in the DM20 Protocol MCP Server, which means it retrieves data without modifying state.
Register the DM20 Protocol MCP server in PolicyLayer and add a rule for list_enabled_library: 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 DM20 Protocol. Nothing to install.
list_enabled_library 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_enabled_library 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_enabled_library. 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_enabled_library is provided by the DM20 Protocol MCP server (polloinfilzato/dm20-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_enabled_library is one line of DM20 Protocol's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
