frame · WineDbg MCP Server MCP: Risk & Policy

WHAT IT DOES

What frame does on WineDbg MCP Server

AI agents invoke frame to trigger actions in WineDbg MCP Server. 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 frame needs a policy

Selecting a stack frame changes the active context within a live debugging session, affecting subsequent debugger commands and the state of the debugging environment. This is an action that influences execution context rather than merely reading data, placing it in the Execute category. Misuse could interfere with a debugging session or cause unintended behavior in the attached process.

Verdict

frame Rate-limited

frame 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.

FAQ

Questions about frame

What does the frame tool do? +

Select a stack frame. It is categorised as a Execute tool in the WineDbg MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on frame? +

Register the WineDbg MCP Server MCP server in PolicyLayer and add a rule for frame: 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 WineDbg MCP Server. Nothing to install.

What risk level is frame? +

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

Can I rate-limit frame? +

Yes. Add a rate_limit block to the frame 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 frame completely? +

Set action: deny in the PolicyLayer policy for frame. 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 frame? +

frame is provided by the WineDbg MCP Server MCP server (maci0/mcp-winedbg). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
