Remove stored Basecamp credentials.
AI agents call basecamp_logout to permanently remove resources in Basecamp MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call basecamp_logout doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Basecamp MCP Server is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
Remove stored Basecamp credentials. It is categorised as a Destructive tool in the Basecamp MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Basecamp MCP Server MCP server in PolicyLayer and add a rule for basecamp_logout: 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 Basecamp MCP Server. Nothing to install.
basecamp_logout is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the basecamp_logout 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 basecamp_logout. 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.
basecamp_logout is provided by the Basecamp MCP Server MCP server (stefanoverna/basecamp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
