list_projects
AI agents call list_projects to retrieve information from Things Cloud MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
list_projects retrieves or enumerates task projects with no side effects. It matches the Read category pattern of non-destructive data queries. The empty description lowers confidence slightly, but the tool name and API context are unambiguous.
From the tool's definition Tool name 'list_projects' indicates a retrieval operation. The description is empty, but the name clearly suggests querying/listing existing projects without modification.
Attacks that exploit this kind of access
list_projects. It is categorised as a Read tool in the Things Cloud MCP MCP Server, which means it retrieves data without modifying state.
Register the Things Cloud 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 Things Cloud MCP. 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 Things Cloud MCP server (nkootstra/things). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
