What dbg_set_exception_breakpoints does on Breakpoint
AI agents invoke dbg_set_exception_breakpoints to trigger actions in Breakpoint. 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
filters | array | — | Exception filter IDs to enable (default none = clear). Choose from available_filters in the result. |
Parameters from the server's own tool schema.
Why dbg_set_exception_breakpoints is rated High
This tool configures debugger behavior in an active debug session, triggering changes in how the debugger controls program execution flow. It modifies the runtime state of a running debug session (halting on exceptions), which is an Execute-level operation — it affects execution behavior rather than just reading or writing data. It is not destructive or financial, but it does control/alter program execution.
From the tool's definition Enable (replace) the debugger's exception breakpoint filters so execution halts when a matching error/exception is thrown (DAP setExceptionBreakpoints)... Requires a running debug session.
Attacks that exploit this kind of access
The rule that runs dbg_set_exception_breakpoints safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For dbg_set_exception_breakpoints, this is the rule to start with:
dbg_set_exception_breakpoints 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Breakpoint, apply this rule, and every dbg_set_exception_breakpoints call is checked against it from then on.
Questions about dbg_set_exception_breakpoints
Enable (replace) the debugger's exception breakpoint filters so execution halts when a matching error/exception is thrown (DAP setExceptionBreakpoints). Pass the filter IDs to enable; call with no filters (or []) to clear them. The result echoes the active filters and lists available_filters — the exception filters the connected adapter actually advertises. Requires a running debug session. Not gated (it only configures the debugger). Feature-detected: on an adapter that advertises no exceptionBreakpointFilters (e.g. Godot 4.3, which also does not answer the request — it would otherwise time out) it returns a clear "unsupported" message WITHOUT sending anything. It is categorised as a Execute tool in the Breakpoint MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
dbg_set_exception_breakpoints accepts 1 parameter: filters. The full parameter table on this page comes from the server's own tool schema.
Register the Breakpoint MCP server in PolicyLayer and add a rule for dbg_set_exception_breakpoints: 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 Breakpoint. Nothing to install.
dbg_set_exception_breakpoints is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the dbg_set_exception_breakpoints 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 dbg_set_exception_breakpoints. 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.
dbg_set_exception_breakpoints is provided by the Breakpoint MCP server (breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
