      description: 'Get a command to run in an existing terminal to start intercepting HTTP(S) traffic from processes launched in that terminal. Returns shell-specific commands for bash, zsh, fish, etc.',
      inputSchema: z.object({
        proxyPort: z.number().describe('Proxy port to route traffic through'),
      }),
    },
    async ({ proxyPort }) => jsonResult(await client.activateInterceptor('existing-terminal', proxyPort))
  );

• src/httptoolkit-client.ts:101-111 (helper)

  ): Promise<{ result: { success: boolean; metadata?: unknown } }> {
    return this.request(
      'POST',
      `/interceptors/${encodeURIComponent(id)}/activate/${proxyPort}`,
      options || {}
    );
  }
