set_debugger_breakpoint

Instructions

Implementation Reference

• src/mcp-server.ts:1215-1219 (handler)

  The handler for the set_debugger_breakpoint MCP tool. Parses input via DebuggerBreakpointSchema, then calls client.debuggerSetBreakpoints(uri, line, user).

  case "set_debugger_breakpoint": {
    const { uri, line, user } = DebuggerBreakpointSchema.parse(args);
    const result = await client.debuggerSetBreakpoints(uri, line, user);
    return { content: [{ type: "text", text: result }] };
  }

• src/mcp-server.ts:687-700 (registration)

  Registration of the 'set_debugger_breakpoint' tool in the ListToolsRequestSchema handler, defining its name, description, and input schema with uri, line, and optional user parameters.

  {
    name: "set_debugger_breakpoint",
    description: "Set a breakpoint at a specific source location in the debugger",
    inputSchema: {
      type: "object" as const,
      properties: {
        uri: { type: "string", description: "Object source URI (e.g. /sap/bc/adt/programs/programs/ztest/source/main)" },
        line: { type: "number", description: "Line number for breakpoint" },
        user: { type: "string", description: "SAP username (default: current user)" },
        ...SYSTEM_ID_PROP,
      },
      required: ["uri", "line"],
    },
  },

• src/mcp-server.ts:135-139 (schema)

  Zod schema 'DebuggerBreakpointSchema' used to validate the input arguments (uri, line, user) for the set_debugger_breakpoint tool.

  const DebuggerBreakpointSchema = z.object({
    uri: z.string(),
    line: z.number(),
    user: z.string().optional(),
  });

• src/adt-client.ts:484-499 (handler)

  The actual implementation method 'debuggerSetBreakpoints' in AdtClient. Ensures an active debug session exists, then POSTs an XML breakpoint definition to the SAP ADT debugger breakpoints endpoint.

    async debuggerSetBreakpoints(uri: string, line: number, user?: string): Promise<string> {
      this.ensureDebugSession();
      const u = (user ?? this.config.username).toUpperCase();
      const xml = `<?xml version="1.0" encoding="UTF-8"?>
  <dbg:breakpoints xmlns:dbg="http://www.sap.com/adt/debugger">
    <dbg:breakpoint dbg:kind="line" dbg:uri="${this.escapeXml(uri)}" dbg:line="${line}" dbg:user="${this.escapeXml(u)}"/>
  </dbg:breakpoints>`;
      const resp = await this.http.post("/sap/bc/adt/debugger/breakpoints", xml, {
        headers: this.statefulHeaders({
          "Content-Type": "application/xml",
          Accept: "application/xml",
        }),
        responseType: "text",
      });
      return resp.data as string;
    }
