# start_ui Start the Project Guardian Web UI server on demand. Automatically searches for a free port and returns the local HTTP URL. Agent View of the PolicyLayer registry record for `start_ui`. HTML page: https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/start-ui ## Facts - Tool: `start_ui` - Server: Project Guardian MCP (`1999azzar/project-guardian-mcp-server`) — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server.md - Homepage: https://github.com/1999AZZAR/project-guardian-mcp-server - Risk category: Execute (High 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": "start_ui", "arguments": {} } } ``` ## Why start_ui is rated High Launches a web UI server process, triggering external operations with uncertain side effects. From the tool's own definition: "Start server on demand, searches for free port, returns local HTTP URL." ## Use case AI agents invoke start_ui to trigger actions in Project Guardian MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Project Guardian MCP: ```json { "version": "1", "default": "deny", "tools": { "start_ui": { "limits": [ { "counter": "start_ui_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on Project Guardian MCP (37) - `cache_delete` — Destructive — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/cache-delete.md - `delete_data` — Destructive — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/delete-data.md - `delete_entity` — Destructive — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/delete-entity.md - `delete_observation` — Destructive — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/delete-observation.md - `delete_relation` — Destructive — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/delete-relation.md - `close_ui` — Execute — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/close-ui.md - `execute_sql` — Execute — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/execute-sql.md - `initialize_memory` — Execute — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/initialize-memory.md - `scan_container_image` — Execute — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/scan-container-image.md - `stop_ui` — Execute — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/stop-ui.md - `analyze_git_changes` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/analyze-git-changes.md - `cache_get` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/cache-get.md - `cache_scan` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/cache-scan.md - `export_data` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/export-data.md - `get_file_context` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/get-file-context.md - `get_project_guidance` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/get-project-guidance.md - `get_session_context` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/get-session-context.md - `get_timeline` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/get-timeline.md - `inspect_untrusted_text` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/inspect-untrusted-text.md - `list_harness_stores` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/list-harness-stores.md - `open_node` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/open-node.md - `query_data` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/query-data.md - `read_graph` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/read-graph.md - `read_graph_stream` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/read-graph-stream.md - `scan_project_secrets` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/scan-project-secrets.md - `search_nodes` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/search-nodes.md - `sync_central_memory` — Read — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/sync-central-memory.md - `add_observation` — Write — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/add-observation.md - `cache_set` — Write — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/cache-set.md - `create_entity` — Write — https://policylayer.com/tools/1999azzar-project-guardian-mcp-server/create-entity.md - …and 7 more: https://policylayer.com/tools/1999azzar-project-guardian-mcp-server.md ## For agents This record is a snapshot.
