List all projects with optional filtering by status
AI agents call list_projects to retrieve information from Helios-9 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 or queries project data from the system. The verb 'list' and the lack of any mention of creation, modification, or deletion indicate a read-only operation. The optional filtering does not change this classification. There is no destructive, financial, or code execution element.
From the tool's definition Tool name is 'list_projects' and description states 'List all projects with optional filtering by status' — this is a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all projects with optional filtering by status. It is categorised as a Read tool in the Helios-9 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Helios-9 MCP Server MCP server in PolicyLayer and add a rule for list_projects: 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 Helios-9 MCP Server. Nothing to install.
list_projects 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_projects 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_projects. 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_projects is provided by the Helios-9 MCP Server MCP server (jakedx6/helios9-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
