Print the backtrace with offsets relative to the base of main.
AI agents call switch_my_bt2 to retrieve information from Gdb Multiarch without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and displays the current call stack (backtrace) relative to the main module's base address. It retrieves existing debug state without modifying memory, executing code, or causing side effects. Similar to gdb_get_backtrace, it is a read/inspect operation.

Attacks that exploit this kind of access
Print the backtrace with offsets relative to the base of main. It is categorised as a Read tool in the Gdb Multiarch MCP Server, which means it retrieves data without modifying state.
Register the Gdb Multiarch MCP server in PolicyLayer and add a rule for switch_my_bt2: 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 Gdb Multiarch. Nothing to install.
switch_my_bt2 is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the switch_my_bt2 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 switch_my_bt2. 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.
switch_my_bt2 is provided by the Gdb Multiarch MCP server (sbergeron42/gdb-multiarch-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
