Part of the Spec Workflow MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

@pimzino/spec-workflow-mcp Destructive Risk 5/5

AI agents may call approvals to permanently remove or destroy resources in Spec Workflow. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

Without a policy, an AI agent could call approvals in a loop, permanently destroying resources in Spec Workflow. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

  approvals:
    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"

What does the approvals tool do? +

Manage approval requests through the dashboard interface. # Instructions Use this tool to request, check status, or delete approval requests. The action parameter determines the operation: - 'request': Create a new approval request after creating each document - 'status': Check the current status of an approval request - 'delete': Clean up completed, rejected, or needs-revision approval requests (cannot delete pending requests) CRITICAL: Only provide filePath parameter for requests - the dashboard reads files directly. Never include document content. Wait for user to review and approve before continuing.. It is categorised as a Destructive tool in the Spec Workflow MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on approvals? +

Add a rule in your Intercept YAML policy under the tools section for approvals. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Spec Workflow MCP server.

What risk level is approvals? +

approvals is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit approvals? +

Yes. Add a rate_limit block to the approvals rule in your Intercept 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 approvals completely? +

Set action: deny in the Intercept policy for approvals. 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 approvals? +

approvals is provided by the Spec Workflow MCP server (@pimzino/spec-workflow-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
