AI agents call projects_list to retrieve information from Vikunja without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about projects without modifying, deleting, or executing any operations. It is a straightforward read-only action that retrieves information the authenticated user is already authorized to see.
From the tool's definition Tool name is 'projects_list' and description states 'List all projects the user has access to' - a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all projects the user has access to. It is categorised as a Read tool in the Vikunja MCP Server, which means it retrieves data without modifying state.
Register the Vikunja MCP server in PolicyLayer and add a rule for projects_list: 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 Vikunja. Nothing to install.
projects_list 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 projects_list 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 projects_list. 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.
projects_list is provided by the Vikunja MCP server (0xk3vin/vikunja-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
projects_list is one line of Vikunja's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
