WHAT IT DOES

What list_projects does on Plane

AI agents call list_projects to retrieve information from Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_projects is rated Low

This tool queries and returns existing project data without modifying, deleting, or executing any operations. It is a standard read operation that retrieves information for display or further processing. The blast radius is minimal—an AI agent misusing this tool would only be able to see projects it already has access to, with no risk of data loss, modification, or unintended execution.

From the tool's definition Tool name 'list_projects' and description 'List all projects in a workspace' indicate a retrieval operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_projects safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_projects, this is the rule to start with:

list_projects Allowed

list_projects is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_projects": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Plane, apply this rule, and every list_projects call is checked against it from then on.

FAQ

Questions about list_projects

What does the list_projects tool do? +

List all projects in a workspace. It is categorised as a Read tool in the Plane MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_projects? +

Register the Plane 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 Plane. Nothing to install.

What risk level is list_projects? +

list_projects is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_projects? +

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.

How do I block list_projects completely? +

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.

What MCP server provides list_projects? +

list_projects is provided by the Plane MCP server (cmet7/plane-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
