AI agents call gdb_elf to retrieve information from Gdb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and inspects ELF binary metadata (headers, sections, symbols, etc.) using analysis tools like pyelftools, readelf, and objdump. These are read-only inspection operations with no side effects, writes, or execution of arbitrary code. Misuse potential is low as it only retrieves static file metadata.

Attacks that exploit this kind of access
Inspect ELF metadata using pyelftools and readelf/objdump helpers. It is categorised as a Read tool in the Gdb MCP Server, which means it retrieves data without modifying state.
Register the Gdb MCP server in PolicyLayer and add a rule for gdb_elf: 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. Nothing to install.
gdb_elf 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 gdb_elf 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 gdb_elf. 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.
gdb_elf is provided by the Gdb MCP server (traver88/gdb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
