WHAT IT DOES

What dbg_set_exception_breakpoints does on Breakpoint

AI agents use dbg_set_exception_breakpoints to create or update resources in Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Breakpoint environment.

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.

RISK

Why dbg_set_exception_breakpoints is rated Medium

An AI agent can call dbg_set_exception_breakpoints faster than any human can review: one bad instruction and it creates or modifies resources in Breakpoint by the hundred, each call as confident as the last.

RECOMMENDED RULE

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 Rate-limited

dbg_set_exception_breakpoints stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about dbg_set_exception_breakpoints

What does the dbg_set_exception_breakpoints tool do? +

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 (which also does not answer the request — it would otherwise time out) it returns a clear "unsupported" message WITHOUT sending anything. Measured: no Godot build this project tests advertises it — 4.3-stable AND 4.7-stable both advertise no filters, so on a shipped engine it is unsupported surface today rather than a feature you can reach; see docs/dap_capability_ledger.json. This sentence used to name 4.3 alone as the example, which read as though a newer build had filters. None does. It is categorised as a Write tool in the Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does dbg_set_exception_breakpoints accept? +

dbg_set_exception_breakpoints accepts 1 parameter: filters. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on dbg_set_exception_breakpoints? +

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.

What risk level is dbg_set_exception_breakpoints? +

dbg_set_exception_breakpoints is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit dbg_set_exception_breakpoints? +

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.

How do I block dbg_set_exception_breakpoints completely? +

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.

What MCP server provides dbg_set_exception_breakpoints? +

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.
