List all AI systems in this workspace with their registration status and evidence coverage.\n\n
AI agents call list_systems to retrieve information from Governance Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing data about AI systems (registration status and evidence coverage) without modifying, deleting, or executing any operations. It is informational only, making it a Read category risk with low severity—the blast radius of misuse is minimal as no state changes occur.
From the tool's definition Tool name 'list_systems' and description 'List all AI systems in this workspace' explicitly indicate a retrieval operation with no side effects. The verb 'list' is a standard read operation.
Attacks that exploit this kind of access
List all AI systems in this workspace with their registration status and evidence coverage.\n\n. It is categorised as a Read tool in the Governance Mcp MCP Server, which means it retrieves data without modifying state.
Register the Governance MCP server in PolicyLayer and add a rule for list_systems: 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 Governance Mcp. Nothing to install.
list_systems 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_systems 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_systems. 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_systems is provided by the Governance MCP server (@mima-ai/governance-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_systems is one line of Governance's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
