MCP cdp_breakpoint_set

Description

Sets a breakpoint at a TypeScript/source line via CDP Debugger.setBreakpoint. The file+line are mapped to the compiled JS location using the session's loaded source map before the CDP call is made.

Delegates internally to debug_breakpoint_set.

Enables the CDP Debugger domain on first use for the current connection.

Required parameters:

• file (string): Local source file path, as returned by cdp_source_list/cdp_source_resolve: absolute, or relative to the session project root (exact match, no suffix matching).
• line (number): 1-based line number in that source file.

Optional parameters:

• condition (string): JS expression; the breakpoint only triggers when it evaluates truthy.
• sessionId (string): Session id returned by cdp_session_create. Uses the active session when omitted.
