List all work package types
AI agents call list_types to retrieve information from Tonle OpenProject 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 and lists existing work package types from OpenProject without creating, modifying, or deleting any data. It is a straightforward query operation with no blast radius if misused by an AI agent.
From the tool's definition Tool name is 'list_types' and description states 'List all work package types' - a pure retrieval operation with no modifications or side effects.
Attacks that exploit this kind of access
List all work package types. It is categorised as a Read tool in the Tonle OpenProject MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tonle OpenProject MCP Server MCP server in PolicyLayer and add a rule for list_types: 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 Tonle OpenProject MCP Server. Nothing to install.
list_types 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_types 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_types. 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_types is provided by the Tonle OpenProject MCP Server MCP server (liratanak/openproject-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
