# views_push Push a view onto the stack of a root view. Agent View of the PolicyLayer registry record for `views_push`. HTML page: https://policylayer.com/tools/karbassi-slack-mcp/views-push ## Facts - Tool: `views_push` - Server: Slack (`karbassi/slack-mcp`) — https://policylayer.com/tools/karbassi-slack-mcp.md - Homepage: https://github.com/karbassi/slack-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "views_push", "arguments": {} } } ``` ## Why views_push is rated Medium This tool creates or modifies UI state in Slack by pushing a view onto a stack. While reversible (views can be popped or dismissed), it modifies application state and could be misused to create misleading UI, inject content, or disrupt user experience. It does not delete data (Destructive), execute arbitrary code (Execute), or move money (Financial), making Write the appropriate category. From the tool's own definition: "Tool name 'views_push' and description 'Push a view onto the stack of a root view' indicates modification of UI state by adding/stacking a view, which is a reversible write operation affecting Slack's interface layer." Risk signals: Admin/system-level operation ## Use case AI agents use views_push to create or update resources in Slack, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Slack environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
