Implementation Reference

• src/tools/suiteRuns.ts:170-214 (handler)

  The complete tool definition for 'stop_suite_run', including handler logic that invokes the BugBug API to stop the suite run and formats the response as MCP content.

  export const stopSuiteRunTool: Tool = {
    name: 'stop_suite_run',
    title: 'Stop a running BugBug suite run',
    description: 'Stop a running BugBug suite run',
    inputSchema: z.object({
      runId: z.string().describe('Suite run UUID to stop'),
    }).shape,
    handler: async ({ runId }) => {
        try {
  
          const response = await bugbugClient.stopSuiteRun(runId);
          
          if (response.status !== 200) {
            return {
              content: [
                {
                  type: 'text',
                  text: `Error: ${response.status} ${response.statusText}`,
                },
              ],
            };
          }
  
          const status = response.data;
          
          return {
            content: [
              {
                type: 'text',
                text: `**Suite Run Stopped:**\n\n- **ID:** ${status.id}\n- **Status:** ${status.status}\n- **Last Modified:** ${status.modified}\n- **Web App URL:** ${status.webappUrl}`,
              },
            ],
          };
        } catch (error) {
          return {
            content: [
              {
                type: 'text',
                text: `Error stopping suite run: ${error instanceof Error ? error.message : 'Unknown error'}`,
              },
            ],
          };
        }
      }
  };

• src/tools/index.ts:11-33 (registration)

  Registration of all tools, including stop_suite_run from suiteRunsTools, using server.registerTool with the tool's name, schema, and handler.

  export function registerAllTools(server: McpServer): void {
    const tools: Record<string, Tool> = {
      ...configTools,
      ...testsTools,
      ...testRunsTools,
      ...suitesTools,
      ...suiteRunsTools,
      ...profilesTools,
      ...advancedTools,
    };
  
    for (const t in tools) {
      server.registerTool(
        tools[t].name,
        {
          description: tools[t].description,
          inputSchema: tools[t].inputSchema,
          annotations: { title: tools[t].title },
        },
        (args: unknown) => tools[t].handler(args as unknown)
      );
    }
  }

• src/tools/suiteRuns.ts:174-176 (schema)

  Zod input schema for the stop_suite_run tool, validating the runId parameter.

  inputSchema: z.object({
    runId: z.string().describe('Suite run UUID to stop'),
  }).shape,

• src/services/bugbugClient.ts:187-189 (helper)

  BugBug API client helper method that performs the HTTP POST request to stop the suite run.

  async stopSuiteRun(id: string): Promise<ApiResponse<BugBugSuiteRun>> {
    return this.makeRequest(`/suiteruns/${id}/stop/`, 'POST');
  }
