# read_registers Read CPU register values. Agent View of the PolicyLayer registry record for `read_registers`. HTML page: https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/read-registers ## Facts - Tool: `read_registers` - Server: Frida Game Hacking MCP (`0xhackerfren/frida-game-hacking-mcp`) — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp.md - Homepage: https://github.com/0xhackerfren/frida-game-hacking-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "read_registers", "arguments": {} } } ``` ## Why read_registers is rated Low Reading CPU registers is a passive inspection operation that retrieves state information without side effects. Although the broader Frida server enables destructive capabilities (memory modification, code injection), this specific tool only reads register values, making it a Read category risk. From the tool's own definition: "Tool name and description explicitly state 'Read CPU register values' — a data retrieval operation with no modification or execution of code." ## Use case AI agents call read_registers to retrieve information from Frida Game Hacking MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Frida Game Hacking MCP: ```json { "version": "1", "default": "deny", "tools": { "read_registers": {} } } ``` ## Other tools on Frida Game Hacking MCP (41) - `clear_scan` — Destructive — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/clear-scan.md - `attach` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/attach.md - `call_rpc` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/call-rpc.md - `detach` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/detach.md - `focus_window` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/focus-window.md - `hook_function` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/hook-function.md - `hook_native_function` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/hook-native-function.md - `intercept_module_function` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/intercept-module-function.md - `load_script` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/load-script.md - `remove_breakpoint` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/remove-breakpoint.md - `replace_function` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/replace-function.md - `resume` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/resume.md - `send_key_to_window` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/send-key-to-window.md - `set_breakpoint` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/set-breakpoint.md - `spawn` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/spawn.md - `unload_script` — Execute — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/unload-script.md - `check_installation` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/check-installation.md - `get_documentation` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/get-documentation.md - `get_module_exports` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/get-module-exports.md - `get_module_imports` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/get-module-imports.md - `get_module_info` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/get-module-info.md - `get_scan_results` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/get-scan-results.md - `get_session_info` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/get-session-info.md - `list_breakpoints` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-breakpoints.md - `list_capabilities` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-capabilities.md - `list_hooks` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-hooks.md - `list_memory_regions` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-memory-regions.md - `list_modules` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-modules.md - `list_processes` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-processes.md - `list_windows` — Read — https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp/list-windows.md - …and 11 more: https://policylayer.com/tools/0xhackerfren-frida-game-hacking-mcp.md ## For agents This record is a snapshot.
