gdb_interrupt · Gdb Multiarch MCP: Risk & Policy

WHAT IT DOES

What gdb_interrupt does on Gdb Multiarch

AI agents invoke gdb_interrupt to trigger actions in Gdb Multiarch. 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.

WHY IT NEEDS A POLICY

Why gdb_interrupt needs a policy

This tool sends an interrupt signal to a running process, causing it to pause execution. It triggers an external operation (signal delivery) on a running program. While not destructive or financial, it actively changes the state of an executing process, making Execute the most appropriate category. Misuse could disrupt active debugging sessions or affect the target program's execution flow.

Verdict

gdb_interrupt Rate-limited

gdb_interrupt stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Gdb Multiarch, so you can run agents against it safely.

FAQ

Questions about gdb_interrupt

What does the gdb_interrupt tool do? +

Interrupt (pause) a running program. It is categorised as a Execute tool in the Gdb Multiarch MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on gdb_interrupt? +

Register the Gdb Multiarch MCP server in PolicyLayer and add a rule for gdb_interrupt: 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.

What risk level is gdb_interrupt? +

gdb_interrupt is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit gdb_interrupt? +

Yes. Add a rate_limit block to the gdb_interrupt 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.

How do I block gdb_interrupt completely? +

Set action: deny in the PolicyLayer policy for gdb_interrupt. 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.

What MCP server provides gdb_interrupt? +

gdb_interrupt 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.
